Some kind of reference problem

I have a simple flash email form similar to the email php tutorial on this site. However, my form gets loaded in a movie clip on my main page/movie… my problem is…I’m using

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

on my movieclip form to take my movie to the second frame which is the “your message has been submitted” page

if I open my form contact.swf in a browser by itself it works just fine, but when I tryout my form as loaded in my main movie, the email still works and the form gets sent, but the contact.swf movie never progresses to the next frame… any thoughts?
