question

I am getting the following error when I change the expression to include additional value. I have added parenthesis in many places but can't figure it out. Any help is appreciated. [rsCompilerErrorInExpression] The Value expression for the textbox ‘textbox260’ contains an error: [BC30455] Argument not specified for parameter 'FalsePart' of 'Public Function IIf(Expression As Boolean, TruePart As Object, FalsePart As Object) As Object'. This expression works: =sum(cdec(iif(Fields!Call_Report_Code.Value = "1D " and Fields!Collateral_Code.Value = 918 and Fields!Payment_Code.Value > "1" , Fields!Query_Balance.Value, 0))) I get the error when I change to the following: =sum(cdec(iif(Fields!Call_Report_Code.Value = "1D " and Fields!Collateral_Code.Value = 918 or Fields!Collateral_Code.Value = 973 or Fields!Collateral_Code.Value = 974 and Fields!Payment_Code.Value > "1", Fields!Query_Balance.Value, 0)))
