_root.next frame PROBLEM

I have a main movie I load external swf’s into via on (release) {
All of this works but one of my movies has a form on it, all I need it to do is goto next fram after submit button is clicked I cant seem to figure out the right path to send the _mc on. This is what I have but it doesn’t work and I know it needs something else after _root. but I dont know what.


Here is my .fla It was too big to upload so I put it on my server if you need it
