In a SSRS 2012 existing report, I am getting the following error message when the value selected by the user should be:
Parameters!pGrade.Value = "KG".

"The Hidden expression for the tablix 'Tablix3' contains an error: The query returned no rows. The expression therefor evaluates to null."

The error message could occur on one of the iif statement(s):

1. hidden property on Tablix3 =iif(Parameters!pGrade.Value = "KG" OR Parameters!pGrade.Value = "01", False, True)

2. expression on one of the group header rows =iif(Parameters!Team.Value = "ALL","ALL", Parameters!Team.Value)

Can you tell me which iif statement could be causing the problem and what code should I use to keep the error message from occuring?

The value selected for pGrade parameter was "KG". When the value of '01' was selected for pGrade, no error message was generated. The default error message of saying 'no records' were selected appeared on the report.

Thanks for looking into this error message!
