Photoshop :: Distorting Text

how to distort some lines of text. I have a 3D-looking image. It's a box where the top surface appears to get smaller as it moves back. I am trying to draw a bounding box on the top surface, and then distort the bounding box so that my text will appear to have the proper perspective. However, I cannot access the distort command under "edit" after I've drawn the box or when there is type in the box. All I can is distort the type. But this won't allow me to properly match the perspective. I need to somehow distort the bounding box (independently control all four corners) and then have the type size accordingly.
