In a report, I have the expression :
=iif(Sum( Fields!X_A_1.Value)<>0,(Sum( Fields!X_A.Value)-Sum( Fields!X_A_1.Value))/Sum( Fields!X_A_1.Value),"NA")
This expression product the error
"The value expression for the textbox ‘textbox12’ contains an error: Attempted to divide by zero."
I think it's because reporting execute the expression
(Sum( Fields!X_A.Value)-Sum( Fields!X_A_1.Value))/Sum( Fields!X_A_1.Value)
even if X_A_1 is equal to 0.
I would like reporting to display NA and not "#Error" when X_A_1 = 0
Is there is a way to catch the error in reporting
Is there is a way for reporting not to execute the expression
(Sum( Fields!X_A.Value)-Sum( Fields!X_A_1.Value))/Sum( Fields!X_A_1.Value)
when X_A_1 is equal to 0.
Sorry if my english is not very good

Note: IIF() is a function call and evaluates all arguments (http://msdn.microsoft.com/library/default.asp url=/library/en-us/vblr7/html/vafctiif.asp)
Instead of the pattern =IIF(Y=0, A, X/Y), use =IIF(Y=0, A, X / IIF(Y=0, 1, Y)) to avoid the division by zero.
