Passing parameter from report to subreport in RDLC

This error message hints that either the report parameter has not been passed from the parent report to the child report or that the wrong format of report parameter or an unacceptable value for the report parameter has been passed from the parent to the child report (I mean the subreport when I mean the child report). Can you check the report parameters that are being passed once again?
