Php vs textfile dynamic text

Question

ok i am at the last part of my project. it worked all well and reads all text fields from a text file as seen on :
http://www.myblueranch.com/index2.html
now i am trying to get the same thing working from MYSQL.
Notice that the text file i used for index2.html is called
www.myblueranch.com/trees1.txt
and it was a direct copy/paste from the php page that gave the results from the MYSQL query. (the php query page is:)
www.myblueranch.com/flash_names.php
The problem is i am getting an error in
www.myblueranch.com/index.html
which uses the php to get the text for the dynamic fields.
I get the following error:
TypeError: Error #2007: Parameter text must be non-null.
    at flash.text::TextField/set text()
    at final_fla::MainTimeline/onDataLoad()
    at flash.events::EventDispatcher/dispatchEventFunction()
    at flash.events::EventDispatcher/dispatchEvent()
    at flash.net::URLLoader/onComplete()
my flash movie has 113 buttons called button_1 --> button_113 and 113 dynamic text fields tcname_1-->tcname_113
my AC3 code is the following:
// button links: to all buttons to open in iframe 'tdes'
// link corrosponds to button number
// i have 113 buttons.
    for(var i:int=1;i<=130;i++){
        if(this["button_"+i]){
            this["button_"+i].addEventListener(MouseEvent.CLICK,f);   
    function f(e:MouseEvent):void{
        var n:String=e.currentTarget.name.split("_")[1];
        navigateToURL(new URLRequest("ranch.php?id="+n),"tdes");
// end of button links
//Create the URLLOader instance
    var myLoader:URLLoader = new URLLoader()
    //the data will come as URL-encoded variables
    myLoader.dataFormat = URLLoaderDataFormat.VARIABLES
    //Load using an URLRequest, even beeing local
    myLoader.load(new URLRequest("flash_names.php"))
    //onLoad handler listener
    myLoader.addEventListener(Event.COMPLETE, onDataLoad)
    //Error handling   
    myLoader.addEventListener(IOErrorEvent.IO_ERROR, onIOError)
    myLoader.addEventListener(SecurityErrorEvent.SECURITY_ERROR, onSecurityError)
    //Could be an error or just a message
    myLoader.addEventListener(HTTPStatusEvent.HTTP_STATUS, onHTTPStatus)   
    //add a listener for the complete event
    function onDataLoad(evt:Event){
        trace(evt.target.data.cant);
        for(var i:uint=1; i<evt.target.data.cant; i++){ 
            this["tcname_"+i].text = evt.target.data["tcname_"+i]
            this["tcname_"+i].autoSize="left"
            this["tcname_"+i].multiline = true;
            this["tcname_"+i].wordWrap = true;
            this["tcname_"+i].width = 70;http://forums.adobe.com/post!input.jspa?container=2066&containerType=14
            this["tcname_"+i].visible = false;
            this["button_"+i].addEventListener(MouseEvent.ROLL_OVER, buttonover);
            this["button_"+i].addEventListener(MouseEvent.ROLL_OUT, buttonout);
            trace(i);
// ON ROLLOVER make text field visible and change color
    function buttonover(e:Event){
        var tf:TextField=TextField(this["tcname_"+e.currentTarget.name.split("_") [1]]);
        trace (tf.name);
        tf.visible = true;
        tf.textColor=0xff0000;
// ON ROLLOVER make change color and make invisible
    function buttonout(e:Event){
        var tf:TextField=TextField(this["tcname_"+e.currentTarget.name.split("_") [1]]);
        tf.textColor=0x000000;
        tf.visible = false;
    //error callbacks
    function onIOError(evt:IOErrorEvent){
        trace("IOError: "+evt.text)
    function onHTTPStatus(evt:HTTPStatusEvent){
        trace("HTTPStatus: "+evt.status)
    function onSecurityError(evt:SecurityErrorEvent){
        trace("SecurityError: "+evt.text)

Answer 1

Kenneth this created another problem:
1- i changed the code of the php to make it look like:
&tcname_1=Cherokee SweetGum&tcname_2=cedar&tcname_3=cedar&cant=3
and now i get this error:
Error: Error #2101: The String passed to URLVariables.decode() must be a URL-encoded query string containing name/value pairs.
at Error$/throwError()
at flash.net::URLVariables/decode()
at flash.net::URLVariables()
at flash.net::URLLoader/onComplete()
Also when i do that even when i load from a textfile (i.e. not from MYSQL through php) i see no text at all!!
2- Where did you want me to put these trace lines? if i put them in the end of my ac3 script i get this compile error:
Scene 1, Layer 'Layer 1', Frame 1, Line 97
1120: Access of undefined property evt.
did i do something wrong?
