Actionscript 2 and Flash Publish Settings

Question

Hi Everyone,
I have posted a couple questions as of late and received fantastic support from other members (Thanks K-Glad).
I do have what I'm assuming to be a basic question however I cannot find an answer for it.
I added some login script to a page as listed below.
stop();
eval("$version");
appname="mikesapp"
loadVariablesNum("http://bars.bevinco.com/mike/newlogin.php", 0, "POST");
//This verifys the users status and forwards them to the portion of the website they are authorized to access. Frame 100 = Regional Access, Frame 200 = Franchise Access, Frame 300 = Employee Access and Frame 400 = Denied Access and Back Button
this.onEnterFrame = function () {
    if(_root.checklog == 100){
        _root.gotoAndStop(5);
    if(_root.checklog == 200){
        _root.gotoAndStop(10);
    if(_root.checklog == 300){
        _root.gotoAndStop(15);
    if(_root.checklog == 999){
        _root.gotoAndStop(20);
My Question
When testing this movie, I found that it was not moving to the section of the flash file that is relative to their "authorization level". I.E. I manually had my PHP echo back to flash, advising that REGIONAL ACCESS was used therefore it should be move this user to FRAME 5 of the file.
I found that it was staying stuck on the first frame and not moving beyond the 1st frame which I thought had something to do with the stop(); that is listed at the top of the actionscript.
However, when I changed the FLASH PUBLISH settings from Flash Player 8 to Flash Player 6, it works flawlessly.
I attempted to publish using Flash 7 however it appears FLASH 6 is as high as I can go without loosing it's functionality.
I'm curious WHY and will this limit our users from using the site if they have a lower version of Flash installed on their CPU?
I have attached the project FLA file and the PHP file, being used on the server to manually tell this file that a REGIONAL has signed in or someone with "100" level status.
As always, thanks in advance to anyone that has taken the time to read this post.
Cheers,
Mike

Answer 1

checklog is a string (even though it looks like a number to you).  flash 6 allowed quite a bit more code sloppiness than later versions.  so, it's very common for users to find publishing for fp6 works, while publishing for fp's higher breaks their code.
you should use:
this.onEnterFrame = function () {
    if(_root.checklog == "100"){
delete this.onEnterFrame
        _root.gotoAndStop(5);
    if(_root.checklog == "200"){
delete this.onEnterFrame
        _root.gotoAndStop(10);
    if(_root.checklog == "300"){
delete this.onEnterFrame
        _root.gotoAndStop(15);
    if(_root.checklog == "999"){
delete this.onEnterFrame
        _root.gotoAndStop(20);
