I cant use multitexturing (Windows2k)! Help!

I asked this one or two months ago. I tried all the ways to use multitexturing in my programs but no success. I cant use any multitexture function or constant. Some guys told me to include a file called ‘glext.h’ and I noticed I dont have that file in my PC.
Could that be the reason?

Thx

Me replying to myself? Yep! I found the ‘glext.h’ file in other post. It should work now.
