UV Unwrapping - texture image no longer appearing

I did a simply UV unwrap on a single face and applied a keypad texture to it. I then wanted to apply another texture to a 2nd face. Now none of the texturing is appearing. Would someone be able to tell me what I am doing wrong? File attached. Many thanks

Sorted… I forgot to assign the material to the face.
