Rdlc sub reports in asp.net webforms.

Question

I have a rdlc report in asp.net webforms and in that report I have amount columns which have to be hyperlink and in their action I am calling another rdlc report as sub report. For this I pass the drillthrough values from first report to the second report in labels and send those values to the stored procedure as parameters. The hyperlink values are negative amounts. When I click on the hyperlink to open the sub report it gives the following error in the image. Could anyone help kindly I have tried to resolve it but I am unable to do it.
