The problem I am finding with SPSS is that it only lists the between subjects factor in the little window, for the post hoc tests.
I am specifically interested in some of the within subjects contrasts and some of what would be interaction comparisons (for example variable one level 3 compared to variable two across it's 2 levels). That is where I am coming up against a road block.
