Illegal Operations ? - Data Report

Hi Everybody,

When trying .EXPORTREPORT option of datareport, I get an error message of “Illegal Operation” and VB is exiting itself. The full code is given below. Apart from this, DE1.CONN1, and rptMARKS data report are in this project (not shown here).
If anybody knows what is the error, please give a solution.
