CAN ANYONE DO THIS ?! - Movie Help

I have had flash mx for about a week now and i am trying to create a website. however there is 1 problem i have which is really annoying...

i have created 2 seperate flash movie files .swf and have successfully inputted one of the files into a main flash document.

However when i try to put in the second file in the main document into the next frame it doesnt seem to work... the first file plays then everything stops and the rest of the frames do not work!

If I put in:

Quote:

---

stop();
nextFrame();

then it just flickers

help me please!
