Hi. I need help please. I need to know how to code this in Dreamweaver:

When user clicks on Button 1,
Flash Movie 1 comes up,
swapping out with Image 1
that was already there,
and plays in its entirety.

Then need Flash Movie 1 to stay up
until user clicks on another button,
which will bring back Image 1.

What is the code for this? Don't need explanations, just need to get it done for work.

THANK YOU IN ADVANCE!
