SW 2008 Pro SP 3.1

Hi everyone,

I'm working through the Solidworks 3D Sketching tutorial: Using a 3D Sketch to Create an Oven Rack Frame. (Yes, I'm a newbie).

The problem is that I follow the directions and I get an error when trying to generate the Swept Boss/Base.

The rebuild error says that it can't rebuild because it's intersecting with itself at segment 10.

I've repeated this tutorial 4 times, and keep getting the error. I'd really appreciate it if someone could tell me what I'm doing wrong.
