Open a external swf (form email)?

I´m learning how to work with flash.
I made a form email and i made a swf movie.
Now in another swf with a button i would like to open the form swf movie.
I can do that, i can open external swf. But when the form opens the input text don´t appear, the other form components appear like the send´s button and the simple text field.
Why is that? Can you help me?
Do you understand my question?
What i will have to do?
Thanks for your help.
