B 2.5 Alpha 0 - Textureing a Modle

I’ve been trying to give different parts of a model different textures.
can create different Materials and Textures But cant seem to assign vertices to the textures.
I’m I doing something wrong or is it the build.

I’m using Blender 2.5 Alpha 0

It may or may not have been what that member wanted but I tell you where to look.
