Import external swf

Is there a way to import/include an external swf into a fla
and give it an instance name?

my problems a little different yet same subject,
here's my issue. i've been designing a website by making
links(in the main site) that load external swf files into empty
movieclip. now within the loaded external swf files that were
loaded by my main site(into the empty movieclip), i have links that
i would like to load a swf back into the main site of another empty
movie clip. So for instance. in my MAIN site i have to empty movie
clips. one called Empty one called Container. when i click lets say
the "media link" on my main site it loads an external media swf
file. within the media swf file i have links that i would like to
load "a movie" swf file into Container. I was told about _lockroot
but i can't figure out the exact code for the external swf file to
access the main sites other empty movieclips.
I'm sure its just a little coding mistake, i've tried just to
put _root.loadMovie("movie.swf", "container") but it removes the
whole website design and shows just the movie on the main site.
I hope explained everything..My email is
[email protected]
thanks for reading and giving this time.

Successfully imported external swf, can not put it into movie clip

Hello all,
I have started learning AS3 and gradually getting used to, trying to put external swf into movie clip.
Successfully imported target swf and put into stage, when I publish this I see target swf is playing.
import flash.display.MovieClip;
var BGLoader:Loader = new Loader();
var BGurl:URLRequest = new URLRequest("HomeBG.swf");
BGLoader.load(BGurl);
BGLoader.y = 0;
BGLoader.x = 0;
addChild(BGLoader);
As next step I want to put this swf into movie clip and get more control, but when I publish bellow only I see is empty background, without any errors.
import flash.display.MovieClip;
var BGLoader:Loader = new Loader();
var BGurl:URLRequest = new URLRequest("HomeBG.swf");
BGLoader.load(BGurl);
BGLoader.y = 0;
BGLoader.x = 0;
//addChild(BGLoader);
var animMC = MovieClip(BGLoader.content).getChildAt(0) as MovieClip;
addChild(animMC);
Is anything missing?
Any help would be appreciated, thanks.

You can only access Loader.content after Load completed successfully.
Try this,
import flash.events.Event;
var BGLoader:Loader = new Loader();
var BGurl:URLRequest = new URLRequest("HomeBG.swf");
BGLoader.contentLoaderInfo.addEventListener(Event.COMPLETE, completeHandler);
BGLoader.load(BGurl);
BGLoader.y = 0;
BGLoader.x = 0;
//addChild(BGLoader);
var animMC:MovieClip;
function completeHandler(event:Event)
animMC = event.currentTarget.content;
addChild(animMC);

Is this possible - Import Flash swf which then imports an external swf

Hi,
I was wondering if it's possible to (as the title says) to import an swf which itself imports an external swf?
Explanation - I've got an scrollbar created in flash...and to keep it tidy i've created the scroll 'content' as another swf which is imported into the scrollbar swf.
Whenever i publish/render the project the scroll bar appears but the content does not.
Is it possible to do this?
Captivate > imports flash > which imports external swf
Cheers
Craig.

Yes that shouldn't be a problem at all. You probably won't be able to see it working when you preview the project from within Captivate but if you publish it and manually copy/paste the external swf to the publish directory, it should work just fine.

Importing fl.controls causes external .swfs to crash

Hello,
I've discovered that if I use fl.controls.* classes in my AS3
code, and then load an external .SWF that uses something like
fl.controls.combobox, I will get a crash when clicking on the
combobox.
The crash is as follows:
TypeError: Error #1009: Cannot access a property or method of
a null object reference.
at fl.containers::BaseScrollPane/drawBackground()
at fl.controls::List/draw()
at
fl.core::UIComponent/drawNow()[fl\core\UIComponent.as:1198]
at fl.controls::List/scrollToIndex()
at fl.controls::SelectableList/scrollToSelected()
at fl.controls::ComboBox/open()
at fl.controls::ComboBox/onToggleListVisibility()
I am not creating new fl.controls.* objects in my AS3 code, I
am merely trying to type them correctly so I can reference them in
code. For example, with the following code, the app crashes:
public function getButton(buttonNum:int):Button
return mDialog["button" + buttonNum];
If I change that code to return Object instead of Button, the
code works fine.
Any thoughts???

thanks….maybe it isn't a actual kernel panic….I was not sure what to call it….the old kernel panic were in UNIX code…this is a SYSTEM NEEDS TO BE REBOOTED
and it is only with LIGHTROOM
no other app causes this.
I can't find the copy paste of the actual SYSTEM REPORT
I will try to repeat it…..and copy it for everyone to see today….
thanks
I greatly appreciate your help

Unable to load external swf which has runtime sharing with another swf.

Hi,
I am getting issues on loading external swf say "importer.swf" file into another swf file say "loader.swf" for second time like
ReferenceError: Error #1065: Variable testSymbol is not defined. VerifyError: Error #1014: Class testClass could not be found.
at global$init()
In the external swf "importer.swf", i am trying to import the symbol "testSymbol" from another swf file say "exporter.swf", which exports through runtime sharing option for the symbols.
I am having some buttons in loader.swf file and on each button click i am loading different swf files into the loader.swf after unloading the previous one.
I am able to load and unload different swf files but unable to load the importer.swf file which is sharing symbols from external swf and that too for the second time i.e., when i click the button twice.
When trying to debug with flash debugger, all the other swf files are being unloaded before loading of another swf but the swf which is sharing symbols/classes with another swf is not getting unloaded.
Output when i am trying to load two files example and importer files into loader.swf file on two different button clicks. On first button click example.swf is loaded. On second button click , example.swf is unloaded and importer.swf is loaded which is successful. On first button click again importer.swf is unloaded and example.swf is loaded. On second button click again, example.swf is unloaded and importer.swf is loaded, here i am getting issues shown above.

If i try to open the swf using IE, i am not getting any issues at all. But i need to open this loader.swf in a air application. Also when i use loaderContext for the loader instance i am able to get rid of this issue but i cant use it in my application.
So, please help me in resolving this issue.
Thanks

AS3: How to access and control embedded sounds in an external swf?

I rarely use sounds in AS3/Flash. I am using Flash Pro CS6, but I can't seem to figure out how to access, control (play, stop, etc) sounds embedded in an external SWF loaded into the main SWF.
It's easy to control them when embedded on the main swf. However, on an externally loaded SWR, I get all kinds of errors. For this app, I really need to embed them in the external SWF.
I read several solutions, but none seem to work.
I embed the sound an mp3 file called soundSegment1.mp3 using Flash CS6 import tool and then open the actionscript properties panel on flash to select the class name: SoundSegment1. Then I edit the class code and create a file called SoundSegment1.as and it's saved right next to my document class main.as in the same directory. The code of the SoundSegment1 class looks like this:
package {
    import flash.media.*;
    public class SoundSegment1 extends Sound
        public function SoundSegment1 ()
            // no code in here
        public function playSound()
            var soundSegment1:Sound = new SoundSegment1();
            var channel:SoundChannel = soundSegment1.play();
Then, in my main.as, I have done several attempts to play this sound such as:
var fileLocation:URLRequest = new URLRequest(SWFToLoad); loader.load(fileLocation); loader.contentLoaderInfo.addEventListener(ProgressEvent.PROGRESS, progressListener); loader.contentLoaderInfo.addEventListener(Event.COMPLETE, completeListener); loader.contentLoaderInfo.addEventListener(Event.INIT, initListener);
function initListener(e:Event):void // I also placed this code on the completeListener and it didn't work {      loader.content.soundSegment1.playSound(); // doesn't work. }
I get:
Line XXX 1061: Call to a possibly undefined method playSound through a reference with static type flash.display:DisplayObject.
or, I also read that I should be able to do something like this anywhere in the Main.as file:
var theClass:Class = Class(loader.content.getDefinitionByName("SoundSegment1")); var theSound:theClass = new theClass(); theSound.play() //doesn't work either.
I also tried on the completeListener:
var TheClass:Class = e.target.applicationDomain.getDefinition("SoundSegment1") as Class; var theSound:TheClass = new TheClass();
theSound.play() //doesn't work either.
I get:
ReferenceError: Error #1065: Variable SoundSegment1 is not defined. at flash.system::ApplicationDomain/getDefinition()
I am stuck and I really need to get this to work. I would be genuinely grateful for your help.
Thank you in advance for any help provided. I really need to get it to work, because I can't simply embed them in the main SWF or load them individually externally one by one.
Thanks again!

THANK YOU!
I think your code may be over my head though. I think you are using an anonymous function which is not something I am familiar with (but I want to learn about if it's useful).
I also don't know where the classS came from. I see that it's a parameter sent along with the event, but I don't really see where that came from.
Someone at: http://www.kirupa.com/forum/showthread.php?305098-Playing-a-embedded-sound-in-an-external- swf&p=2658098#post2658098
Is showing what seems to be an easier solution, but my problem there is I can't access the source file of the "child" swf.... ayayay.....
I am going to tinker with your solution and see if it gets me anywhere. Thanks so much for your help again.

Problem with volume handle and external SWF

Hello I'm having 2 problems.
The first is that when loading an external swf in my main SWF I get this in the output window:
TypeError: Error #1009: Cannot access a property or method of a null object reference.
at audio_fla::list_1/frame1()
at flash.display::Sprite/constructChildren()
at flash.display::Sprite()
at flash.display::MovieClip()
at audio_fla::MainTimeline()
TypeError: Error #1009: Cannot access a property or method of a null object reference.
at audio_fla::MainTimeline/frame1()
But it still works. Its an mp3 player.
The other problem is that the loaded SWF has a volume controller. When I test the external SWF by itself it works fine. When I load it on my main SWF when I start to drag the handle on my volume slider and MOUSE_UP outside the handle it still keep dragging the handle.
The code of my main SWF is:

External .swf runtime linkage .pngs AS3

Flash can compress .png files like Photoshop can compress
.jpg files better than any other tool hands down.
I have 77 .png files that are 1.8 .megs on my c: drive after
I imported them and setting the file compression under the "File
> Publish Settings" to 75% for jpg and published the .swf with
all the .png on the stage the file size is 350K that's about 20% of
the original file size of the .pngs downloaded file by file with 77
separate request.
I can create linkage in the shared .swf and test the movie
with code in the shared .swf to add the movieclip holders for each
.png to the stage but when I load the shared .swf into the main
.swf Flash acts like it can't create the classes based on the
linkage I setup or that the MovieClip linkage doesn't exist.
I tried a test to have the shared .swf with all the .pngs and
linked movieclips to add the assets to it's own stage and it works
fine but that means a lot of my code and logic is included in the
shared .swf that the designers need to add .pngs to. It's
unfortunate AS3 sucks but I'm just about done with the project if I
knew what a battle AS3 was going to be I would have stayed with AS2
my next projet will be AS2 no question non at all. Anyway I setup
"class" linkage identifier for each .png with a movieclip holder
for each image. The 20% of the size for the pngs and one request
vs. 77 separate request makes it worth the extra effort of
importing the images, creating a holder movieclip with linkage but
the main .swf that loads the shared .swf with all the assets and
linkage can't see or create the assets like the shared .swf can
when I test it.
We need to have the main .swf get a handle of the linked .png
assets and place them in the main .swf to load the assets to
different parts of the main .swf. It's cute that the shared .swf
can add the linked assets to it's own stage but not too useful.
Also the way we deploy we cannot roll out a new release/build to
update the .pngs but we can upload a new .swf to the asset server
so the .pngs need to be in a separate .swf. I can get the shared
MovieClip to add the linked assets to it's own stage when testing
and when loading my problem is the main .swf that loads the shared
.swf cannot create instances of the classes that are exported for
runtime sharing using linkage.
If it is possible I would like to know how the heck you get a
handle on a linked asset in an externally loaded .swf. Preferably
without creating my own prototyped insane class consisting of mega
libraries of external .as files. Just a way to reference MovieClips
holding pngs that have linkage and are setup for runtime sharing.
It really shouldn't be this hard it's a simple task in AS2. I'm not
looking for a coding competition or some wild class to do the job I
want a few lines of code to create an instance of a class then
reference to the linkage/MovieClip holding the .png to addChild it
into a target movieclip.

I solved it I'm loading 77 embedded assets in an external
.swf that compresses 77 .png images without loosing quality it
works great.

Loading external SWF's into an SWF Loader as3 style?

Hi,
I've recently made the switch from as2 to as3 and am still struggling to get my head around one aspect in particular. I've managed to load one external swf into a blank file via the script
import LoadDisplayObject;
var loader:LoadDisplayObject = new LoadDisplayObject("button_01.swf", true);
loader.addEventListener("displayObjectLoaded", onComplete, false, 0, true);
addChild(loader);
function onComplete(evt:Event):void {
     trace("loaded complete received");
     loader.scaleX = loader.scaleY = .75;
.....however I'm struggling with the script to make a swfs load into a space when one of my 3 buttons is clicked....
My page currently has three buttons (button_01, button_02 and button_03) and in a local folder three separate swfs with the same names which I wish to load in, when the appropriate button is pressed.
I have managed to get them to load in using a tutorial...however they load over the top of each over...far from ideal. From research on the internet I've found a range of different script...but I just can’t find anywhere I can find script to make this work..hence why I have turned to here.
Any help much appreciated...thanks in advance.

Hi,
Just throught I would let you know that I've manged to get this to work this morning. Changed the script slightly and used a different method of:
var home:MovieClip = this;
function butt1Click(evt:MouseEvent):void {
    var ldr:Loader = new Loader();
    ldr.load(new URLRequest("button_01.swf"));
    ldr.contentLoaderInfo.addEventListener(Event.INIT, loaded);
function butt2Click(evt:MouseEvent):void {
    var ldr:Loader = new Loader();
    ldr.load(new URLRequest("button_02.swf"));
    ldr.contentLoaderInfo.addEventListener(Event.INIT, loaded);
function butt3Click(evt:MouseEvent):void {
    var ldr:Loader = new Loader();
    ldr.load(new URLRequest("button_03.swf"));
    ldr.contentLoaderInfo.addEventListener(Event.INIT, loaded);
function loaded(evt: Event):void {
    if(contentClip.numChildren > 0){
        contentClip.removeChildAt(0);
    contentClip.addChild(evt.target.content);
button_01.addEventListener(MouseEvent.MOUSE_UP, butt1Click);
button_02.addEventListener(MouseEvent.MOUSE_UP, butt2Click);
button_03.addEventListener(MouseEvent.MOUSE_UP, butt3Click);
seems to work well. Only small question is if I want one page to load automatically upon opening...how do I alter the script to do this??? Thanks

Remove / unload external swf file(s) from the main flash file and load a new swf file and garbage collection from memory.

I can't seem to remove / unload the external swf files e.g when the carousel.swf (portfolio) is displayed and I press the about button the about content is overlapping the carousel (portfolio) . How can I remove / unload an external swf file from the main flash file and load a new swf file, while at the same time removing garbage collection from memory?
This is the error message(s) I am receiving: "TypeError: Error #2007: Parameter child must be non-null.

Andrei1,
Thank you for the helpful advice. I made the changes as you suggested but I am receiving a #1009 error message even though my site is working the way I wan it to work. I would still like to fix the errors so that my site runs and error free. This is the error I am receiving:
"TypeError: Error #1009: Cannot access a property or method of a null object reference."
I'm sure this is not the best method to unload loaders and I am guessing this is why I am receiving the following error message.
     loader.unload();
     loader2.unload();
     loader3.unload();
I also tried creating a function to unload the loader but received the same error message and my portfolio swf was not showing at all.
     function killLoad():void{
     try { loader.close(); loader2.close; loader3.close;} catch (e:*) {}
     loader.unload(); loader2.unload(); loader3.unload();
I have a question regarding suggestion you made to set Mouse Event to "null". What does this do setting the MouseEvent do exactly? Also, since I've set the MouseEvent to null do I also have to set the loader to null? e.g.
---- Here is my updated code ----
// variable for external loaders
var loader:Loader;
var loader1:Loader;
var loader2:Loader;
var loader3:Loader;
// makes borders resize with browser size
function resizeHandler(event:Event):void {
// resizes portfolio page to center
     loader.x = (stage.stageWidth - loader.width) * .5;
     loader.y = (stage.stageHeight - loader.height) * .5;
// resizes about page to center
     loader3.x = (stage.stageWidth - 482) * .5 - 260;
     loader3.y = (stage.stageHeight - 492) * .5 - 140;
//adds gallery.swf to stage at begining of moviie
     Down();
//PORTFOLIO BUTTON
//adds eventlistner so that gallery.swf can be loaded
     MovieClip(root).nav.portfolio.addEventListener(MouseEvent.MOUSE_DOWN, Down, false, 0, true);
function Down(event:MouseEvent = null):void {
// re adds listener for contact.swf and about.swf
     MovieClip(root).nav.info.addEventListener(MouseEvent.MOUSE_DOWN, Down1, false, 0, true);
     MovieClip(root).nav.about.addEventListener(MouseEvent.MOUSE_DOWN, Down3, false, 0, true);
//unloads gallery.swf from enter frame if users presses portfolio button in nav
     var requester:URLRequest=new URLRequest("carouselLoader.swf");
     loader = new Loader();

     loader.x = (stage.stageWidth - 739) * .5;

Need help unloading an External .swf within another external .swf

My main project loads an external .swf ("room") depending on which button the user clicks. Once that external .swf ("room") is loaded, the viewer chooses a ("demo") .swf to view. I need the "demo" .swf to unload once it is finished playing so that the viewer sees the 1st external .swfs menu again. All .swfs are loaded into an empty loader component. The "demo" swfs were created in captivate thus I don't have access to a timeline for them.
I imported a .swf into captivate that will call a function at the end ie..._root.unloadCaptivate();
and I have the following code in the originally loaded .swf
function unloadCaptivate() {
mcLoader.unloadClip(accountingLoader_mc);
btnEndPeriod_btn.enabled = true;
btnCashCollect_btn.enabled = true;
btnFinancialMGMT_btn.enabled = true;
_root.btnHome_mc._visible = false;
btnAcct_mc._visible = false;
btnPlay._visible = false;
btnPause._visible = false;
That all works fine, but when I load "room" .swfs into the main .swf, the unloadCaptivate(); no longer works...any ideas? Thanks!

you should be able to use a loop (like onEnterFrame) to check when your demo swf's _currentframe==_totalframes.

Design/gallery website - loading external SWF asset on splash page

Hello all,
This forum has been such a help with my website, i've found the answers to hundereds of questions but I've hit a bit of a brick wall and I wonder if anyone can help me.
I have recently built a website http://www.intivision.co.uk/ using illustrator/flash/flash catalyst. It's still a work in progress and I'm happy with the gallery pages and general functionality but I'm having major issues with my splash/load screen and a few other niggles.
The animation on the front page is a looping photo gallery i created in flash (as a .SWF) and imported into Catalyst. It is designed to play (and loop) indefinately after 2seconds of loading the title page. Half the time I access the site the animation does not load at all and just shows a blank screen and my logo. It will appear once the page is refreshed. A very bad first impression.
I have a feeling this is because the SWF is externally loading the asset (which is only 350kb). Is there a solution or a way to imbed this animation so the entire project won't 'play' until this intro is loaded?
Thanks - Tom
ps Any other comments would be greatly appreciated

Thanks for taking your time! Much appreciated.
I like not complicated :-) So it is now loading from the start - stretching over the whole timeline. How do I controll the visibility during the "HOME" = that is invisible?
This is the code I use to load the external swf:
var Xpos:Number=0;
var Ypos:Number=0;
var swf:MovieClip;
var loader:Loader=new Loader();
var defaultSWF:URLRequest=new URLRequest("main_movie_241x700.swf");
loader.load(defaultSWF);
loader.x=Xpos;
loader.x=Ypos;
addChild(loader);

Loading an External SWF Files not working

Hello,
So I have a project I am working on in which I would like to teach how to cash a scratch off card. I have made the scratch and made it so it will "scratch"
Before:                                                                                                                                               After:
Now I have saved this out and am trying to load this into my "holder" however I am getting an error:
TypeError: Error #1009: Cannot access a property or method of a null object reference.
    at ScratchTicket()
When I use this code:
stop();
import flash.events.MouseEvent;
nextPG_btn.addEventListener(MouseEvent.CLICK, nClick);
lastPG_btn.addEventListener(MouseEvent.CLICK, lClick);
function nClick(event:MouseEvent):void{
    nextFrame();
function lClick(event:MouseEvent):void{
    gotoAndStop(3);
var mcExt:MovieClip;
var ldr:Loader = new Loader();
ldr.contentLoaderInfo.addEventListener(Event.COMPLETE, swfLoaded);
ldr.load(new URLRequest("ScratchTicketOnly.swf"));
function swfLoaded(e:Event):void {
    mcExt = MovieClip(ldr.contentLoaderInfo.content);
    ldr.contentLoaderInfo.removeEventListener(Event.COMPLETE, swfLoaded);
    mcExt.x = 50;
    mcExt.y = 50;
    addChild(mcExt);
What am I doing wrong?
Is it because of my coding in the External SWF?
package {
    import flash.display.Sprite;
    import flash.display.MovieClip;
    import flash.events.MouseEvent;
    import flash.ui.Mouse;
    public class ScratchTicket extends MovieClip{
        var scratcherIsActive:Boolean= false;
        var stuffUnderMask:Sprite = new Sprite();
        // init class
        public function ScratchTicket():void{
            stage.addEventListener(MouseEvent.MOUSE_DOWN, mouseIsDown);
            stage.addEventListener(MouseEvent.MOUSE_MOVE, mouseIsMoving);
            stage.addEventListener(MouseEvent.MOUSE_UP, mouseIsUp);
            // make mask
            stuffUnderMaskClip.mask = stuffUnderMask;
            addChild(stuffUnderMask);
            makeCursor();
        // helper functions
        private function makeCursor():void{
            trace("Custom cursor can go here");
        // hover effects
        private function mouseIsDown(e:MouseEvent):void{
            //Mouse.hide();
            Mouse.cursor="hand";
            scratcherIsActive = true;
        private function mouseIsUp(e:MouseEvent):void{
            //Mouse.show();
            Mouse.cursor="arrow";
            scratcherIsActive = false;
        private function mouseIsMoving(e:MouseEvent):void{
            if(scratcherIsActive){
                stuffUnderMask.graphics.beginFill(0x000000);
                stuffUnderMask.graphics.drawEllipse(mouseX, mouseY,60, 60);
                stuffUnderMask.graphics.endFill();
    }// class
}// package
Any help is great!

Make sure you check for errors on loading..
import flash.events.IOErrorEvent;
ldr.contentLoaderInfo.addEventListener(IOErrorEvent.IO_ERROR, uhOhError);
function uhOhError(e:Event):void
     trace(e);
     // probably put some visual text field here to display the error
Aside that, on the first block of code mentioned, is that a frame script or running from somewhere in a class? If in a class and it doesn't extend a display object then you can't addChild(mcExt) without erroring.

Unloading an External SWF

Hi,
I'm building a site that has 7 sections. 1 section is a Photo Gallery for which I'm loading an external SWF file that is controlled by an XML file. Im doing this for allowing content editing any time.
All of the other content on the site is one-time, no backend required.
I've successfully loaded the external swf file into a loader in one of the frames. However, when I navigate away to the other 6 sections, I'm unable to unload the external SWF loader. How do I go about this?
Here's my code that loads the external SWF in one frame:
import flash.events.MouseEvent;
//This creates a new instance of the loader object.
var my_Loader:Loader = new Loader();
//This creates a new instance of the URLRequest object that contains the
//path to the external SWF.
var my_url:URLRequest=new URLRequest("gallery.swf");
//These listeners detect when the file has finished loading, and if the
//correct file is loaded.
my_Loader.contentLoaderInfo.addEventListener(Event.COMPLETE, finishLoading);
my_Loader.contentLoaderInfo.addEventListener(IOErrorEvent.IO_ERROR, errorHandler);
//The load method then loads the SWF file into the loader object.
my_Loader.load(my_url);
//This will offset the load SWF file, so be appear at (20, 20) on the stage.
my_Loader.x = 37.85;
my_Loader.y = 74.90;
//This function adds the external SWF to the stage.
function finishLoading(loadEvent:Event) {
addChild(loadEvent.currentTarget.content);
//This function displays a message if the file is not found.
function errorHandler(errorEvent:Event):void {
trace("file missing");
stop();
Here's the code I'm using for the site navigation buttons. I tried adding my_Loader.unload(); for all of the button Event listener functions. Its still not working.
import flash.events.MouseEvent;
vinaybtn.addEventListener(MouseEvent.CLICK, vinay);
function vinay(event:MouseEvent):void
    my_Loader.unload();
    gotoAndStop(2);
priyabtn.addEventListener(MouseEvent.CLICK, priya);
function priya(event:MouseEvent):void
    gotoAndStop(3);
gallerybtn.addEventListener(MouseEvent.CLICK, gallery);
function gallery(event:MouseEvent):void
    gotoAndStop(4);
bestwishesbtn.addEventListener(MouseEvent.CLICK, bestwishes);
function bestwishes(event:MouseEvent):void
    my_Loader.unload();
    gotoAndStop(5);
invitationbtn.addEventListener(MouseEvent.CLICK, invitation);
function invitation(event:MouseEvent):void
    gotoAndStop(6);
rsvpbtn.addEventListener(MouseEvent.CLICK, rsvp);
function rsvp(event:MouseEvent):void
    gotoAndStop(7);
Any help would be much appreciated.
Thanks,
Sudarshan

try:
var mc:MovieClip;
//This function adds the external SWF to the stage.
function finishLoading(loadEvent:Event) {
mc=loadEvent.currentTarget.content as MovieClip;
addChild(mc);
vinaybtn.addEventListener(MouseEvent.CLICK, vinay);
