Can someone provide some insight why I am getting this error:

"Overload resolution failed because no accessible 'IIf' accepts this number of arguments"

Here is the IIf statement:

=iif(Sum(Fields!CallsRemaining.Value))<0,1,((Sum(Fields!TotalInventory.Value)+Sum(Fields!CallsRemaining.Value))/(Sum(Fields!TotalInventory.Value)))

It only has 2 arguments, so not sure why overloading. Any suggestions would be greatly appreciated.

Thanks.

回答1:

Parenthesis was in the wrong place. Fixed with simple move:

=iif(Sum(Fields!CallsRemaining.Value)<0,1,((Sum(Fields!TotalInventory.Value)+Sum(Fields!CallsRemaining.Value))/(Sum(Fields!TotalInventory.Value))))
