url links to SSRS reports

I have a sql server which hosts three groups of reports. Rather than linking to the reports manager page which shows all three report groups I decided I would like to link directly to a report group.

Here's the URI which i'm passing (this is coming from a silverlight usercontrol with a button click event) http://localhost/Reports/Pages/Folder.aspx?ItemPath=%2fConveyor+Reports&ViewMode=List but instead it sends me to http://localhost/Reports/Pages/Folder.aspx

In that link ^ i'm trying to link into the "Conveyor Reports" group directly. But the end result is always redirecting me to Reports Manager homepage.

I modified my formatting to

http://localhost/Reports/Pages/Folder.aspx?ItemPath=/Conveyor%20Reports

and it worked.
