Small gradient problem

I just drew a square in PS and now I want to use the gradient tool on it but it says it is not directly editable. Any suggestions? Sorry for the small question but I am working on a deadline and my Illustrator wont work~! And when i draw a square in one layer, it wont let me draw another in the same layer. Please help… i dont know what to do

I also cant find the export option to flash?! I am in big trouble here
