I am new to SSRS and trying to write an IIF statement. My Crystal If Then statement is as follows:if {Field_line1} = "" then {Field_account_desc} else{Field_line1}. This works fine. In SSRS I wrote an IIF statement=iif(Fields!line1.Value = "",Fields!account_desc.Value,Fields!line1.Value). This does not work. If the line is blank then it just stays that way. I have tried IsNothing Empty IsNull DBNull and nothing seems to work. Can someone help?
