Dear list
My design is quite simple two independent variables A and B each with two levels(1 or 2).I performed ANOVA
UNIANOVA
  y BY a b
  /METHOD = SSTYPE(3)
  /INTERCEPT = INCLUDE
    /PRINT = DESCRIPTIVE
  /CRITERIA = ALPHA(.05)
   /DESIGN =a b a*b .

The interaction is significant and I want to test the simple effects of B.
That is, to perform  two contrasts the first between the two levels of B for A=1 and the second between the two levels of B for A=2.
What is the syntax that I should use for this contrast?

I will appreciate any help

Thanks
