Hey Thom:
The above URl works fine.. But I need it to open in a new browser window ( or tab ) 

. I wanted to now call this link from another SSRS report and have it open in a new browser window. So I followed a help tip in the internet and added the following:  When i click on the cell it does not do anything......

See the attached 2 images and leg me know whether I am doing something wrong 


="void(window.open('http://mhpdw2/ReportServer/Pages/ReportViewer.aspx?%2XXXXXXXXXXX%2fDO_NOT_USE%2fSubReportWithMemberInfoUsedByWaiverFinance&rs:Command=Render&RepParameterSet=" + "50,>64,E," + Fields!YYYYMM.Value + "')"
