Problem in MS CRM 4.0 with Expand/Collapse on a SSRS 2008 report

Question

Hello,

I'm working on a SSRS report wich is deployed in a IFRAME in MS CRM 4.0. The deployement works, the report is available in the IFRAME.

I have two linked problems (in my opinion):

• The function Expand/Collapse works in SSRS, but not in my CRM's IFRAME.

• The report contains parameters. Changing their values doesn't work in MS CRM, but do work in SSRS viewer and in the report manager.

Any idea?

thanks in advance (sorry for my poor english)
