Email PHP problem

i followed the kirupa’s email tut. I can receive the information but i cant get my confirmation. i have searched the forums and i have read similar things but for some reason i still have a problem with it. The form is inside a movieclip (contactForm) and this swf is then loaded into another emptymovieclip (window) on the main timeline. this is what i have on my send button:

on (release) {
// send variables in form movieclip (the textfields)
// to email PHP page which will send the mail
_root.window.contactForm.form.loadVariables(“email.php”, “POST”);
}

and this on my form tag:

onClipEvent(data){
// show welcome screen
_root.window.contactForm.form.nextFrame();
}

i know my paths are correct and that was the problem that i was seeing in alot of the posts but i dont understand why i still cant get the confirmation frame?

if anyone could please help me figure this out, greatly appreciated
