Report not showing

I'm calling a report service using a javascript, unfortunately, it did not display the report and still asking for the value of my parameter. Here's the link that was generated in my popup window http://myserver-pc/Reports_myserver/Pages/Report.aspx?ItemPath=%2fINVReport%2freportsheet&rs:Command=Render&rc:parameters=false&sheetid=0001

Is there's something missing with the link?
