I have a parameter 'Section' which has values A,B,C and another parameter 'Field' which has values X,Y,Z. now my requirement is i need to make column visibility based on both the parameters,if my parameter 'section' is A and parameter 'field' is X then the column should be shown else hidden.both are multi-valued parameters. I have written the following expression which is not allowing me to run
=IIF(InStr(JOIN(Parameters!Sections.Label,", "),"A"),InStr(JOIN(Parameters!Fields.Label,", "),"X", False,True),True)
Error i am getting while running the report is "Input string was not in a correct format. Can anyone help me in correcting the format?
