Very simple question: applying normal maps

I have never used the game engine before. Just want to do one very simple thing. How do I apply a normal map in the game engine?

I have the material set up for normal mapping and everything - renders with the normal map applied. I push the textured button, switch into game mode. My model is completely white with no normal map applied. How do I get the normal map to show up?

Thanx!

enable GLSL first if your vide ocard allows it
