i know i can do this but i cant remember how to do a horizontal repeating top header image AND tiled background image ( like a texture background tile)

i have used the tweakset 7 for the horizontal repeating top header image but it breaks if you add a pasteboard colour or background image

please can somebody help me i'm feeling so damn stupid i have done it before and i just cant remember the trick

the tweakset shows how you can add a colour but i need a repeating tile
