how do i link to report and pass values to SP

Yes I'm a Newbie.

I would like to use a LinkButton or Hyperlink from my web page to call/open a Crystal Report. The report is already made and linked to my SQL Stored Procedure. I know this because I saw the datafield populate in the report disgn when I created it.

What link should I use (linkbutton or hyperlink) and how?

How to I pass values to the Stored Procedure?
Are the values passed from the report page or with the link button?

Thanks in advance for your time.
