I've been reading tutorials and I see that I need to type in some code. My problem is that when I try to start the code, the program isn't giving me any place to type in the code.

I'm simply trying to make a sprite move around the screen. Basic up, down, left, and right movements. I see what the code is to do so...just don't know why I can't type in anything. Am I doing something wrong or is flash acting funny on me? Thanks!!!
