Having problems texturing.

I get this error when i go into texture mode on my cube, Whenever I try to texture it, only the white sides get textured, and all the others get left blank, like you see in the photos. Can anyone help me with this?

Probably you don’t have a UV map.

Are the sides of the cube illuminated by a lamp. It looks lke you have a lamp pointing straight down which won’'t light the sides of the cube.

That seems to be it, thank you.
