Dynamic hyperlink in Reporting Services 2008

I had a custom entity - project and was needed to open a project card from the report.
So I had done exactly as saying in http://msdn.microsoft.com/en-us/library/ms157159.aspx and in the expression field of hyperlink I was typed next

="http://SERVERNAME/ORGANIZATIONNAME/userdefined/edit.aspx?id=%7b" & Fields!projectid.Value.ToString() & "%7d&etc=10005"

SERVERNAME and ORGANIZATIONNAME must be replaced with your crm values.
