Reporting Services Problem

I have a URL link to a report such as in a html page. Here is a typical example

<a href = "List">http://www.myserver.com/ReportServer?%2fCustomReports%2fOrganization>List of Managers</a>

This works great and renders the report

However after I return to the calling page and perform a POST such as

<form ACTION="http://www.myserver.com/Catch.asp" METHOD="post" name="frm1" id="frm1"
<INPUT id=Var1 name = Var1 type=hidden value="valuetopost">

The variables Var1 are never passed if I do this AFTER linking to the report. It always works if I do this BEFORE calling the report. I can only get this to work again by closing out the html page and starting again

Does anyone have any ideas what is wrong?You should try posting this to SQL Server Reporting Services forum.
