Getting "infinity" when running this expression

When I run this expression, percentage, I'm still getting infinity as my
return when I have a zero in one of the columns
=IIF(SUM(IIF(DATEPART("yyyy",Fields!APR_DT.Value) = DATEPART("yyyy",NOW()),
Fields!APR_CNT.Value,0))-SUM(IIF(DATEPART("yyyy",Fields!APR_DT.Value) = DATEPART("yyyy",NOW())-1, Fields!APR_CNT.Value,0))=0, 0,
SUM(IIF(DATEPART("yyyy",Fields!APR_DT.Value) = DATEPART("yyyy",NOW()),
Fields!APR_CNT.Value,0))-SUM(IIF(DATEPART("yyyy",Fields!APR_DT.Value) = DATEPART("yyyy",NOW())-1, Fields!APR_CNT.Value,0))) /
IIF(SUM(IIF(DATEPART("yyyy",Fields!APR_DT.Value) = DATEPART("yyyy",NOW())-1,
Fields!APR_CNT.Value,0)) = 0, 1, SUM(IIF(DATEPART("yyyy",Fields!APR_DT.Value)
= DATEPART("yyyy",NOW())-1, Fields!APR_CNT.Value,0)))
Any ideas where I'm screwing up... Thanks in advanceThe IIF is a VB function. All function arguments are evaluated immediately
before the function is called. So this will fail: IIF(1 = 1, 1/1, 1/0) even
though it seems like 1/0 should not be evaluated because the condition (1=1)
is true.
This is what most likely happening in your expression.
