(url cause the pic was kind of big for the post.) and i made this small cause i felt like it :l

can someone tell me how to fix this problem?

no added verts? turned off normals?

Normals is what got me when I tried to start modelling.

ok. it was the normals that got me. i have it working in game now.
thank you for the help.
