Mix Material Alpha Question

[coenbrasser]

Im running into some problems working with mix materials and alphas.

For some reason I cant get a checkerboard blue texture to be on top of the orange mix material:

So i want the first mix material (orange) to mix with the blue checkerboard texture on top, but how do I fix this?
