syntec issue: opening link report with parameters in a new browse window.

"javascript:void(window.open('http://myservername/Pages/ReportViewer.aspx?%2fRPTS%    2fTrend_Detail&rs:Command=Render
&root_cause="+Fields!Root_Caus开发者_StackOverflowe.Value+"
&level_0="+Fields!Level_0_Results.Value+"
&level_1="+Fields!Level_1_Results.Value+"
&level_2="+Fields!Level_2_Results.Value+"
&year_month_nbr="+Fields!year_month_nbr.Value+"
&IssueSource="+Join(Parameters!IssueSource.Value,"&IssueSource=")"+
'))"

If i leave the &IssueSource="+Join(Parameters!IssueSource.Value,"&IssueSource=")"+ line out i get a message: user-defined value for the report parameter 'IssueSource'.

Your quotes are off at the end. Try

&IssueSource="+Join(Parameters!IssueSource.Value,"&IssueSource=")+
"'))"
