OpenGL Game Programming ....

Hey, I''m working on a terrain engine, with which I have 0 experience, and i''m using the heightfield terrain from chapter 8 to get started. The problem is that the lighting isn''t working. I have the lighting set up but i realized that in the book they don''t set the normals. So, i''ve been trying for a while to do that but I''m having trouble finding the cross product of each trianlge and passing it to glNormal3f() If have any advice or maybe know why the lighting isn''t working, i''d be greatly appreciative!
