Desparate for Help with Flash form actionscript

HI everyone,

Just wandering if someone can help on this extremely frustrating problem.

I have a main timeline with a blank movie in it so that I can click the menu and various swf’s load into it. This all works perfectly. Then, I have a contacts page with a form that sends to php which all works perfectly. The thing that doesn’t work is that when I click submit the thank you frame immediately afterwards doesn’t play. The code I’ve typed is:
**
On the Submit Button:**

on (release) {
form.loadVariables(“email.php”, “POST”);
}

On the movie clip:

onClipEvent(data){
_root.nextFrame();
}

This all works fine in Publish preview but once uploaded to the servers it fails unless you type [color=#606420]www.ljmedia.co.uk/contact.swf[/color] then it works fine. Is this something to do with layers and levels etc? I’ve asked so many people but still not solved.

I would appreciate any help whatsoever.

Thanks, Jon
