I got it to work in 8.5!!!!!!!

Evidently you can't reference 2 separate fields in a suppression formula.

if A=1 and B=2 then 1 else 0 (this won't work)

So I put the compound if-then's in a single formula.

if A=1 and B=1 then 99 else

if A=1 and B=2 then 999 else

if A=3 and B=10 then 9999 else 0

Now in the suppression field I use a simple if-then.

if formulavalue = 99 then 1 else 0

On a side note, you can reference the same field twice in a suppression field.

if A=1 or A=2 then 1 else 0

I just had to think a way around the suppression limitation.
