Microsoft Powerpoint 2007 shape fill help?

Click on the box. When you do it automatically opens up the 'drawing tools' ribbon. On the right side is the "drawing tools" group. This is where you need to go. Click the "shape fill" arrow. Then click gradient or texture, and at the bottom of their windows is "more gradients" and "more textures". Click this "more" section and I believe you will find what you are looking for.
