Passing Multi-value Parameter through URL

[sdebo2]

We are using crystal Reports 8, and displaying reports through the URL command as described in the below link.

It works fine for most of the reports including passing single parameters. However I have several reports where I need to pass Multiple values for a parameter. The parameter in the report is set to allow Multiple values, but I am unsure how to structure the URL.

Below is the URL I am using, ‘prompt2’ is the one I want Multiple values for.
server/reportname.rpt?init=actx&prompt0=ALL&prompt1=Date%20(2005,%2003,%201)& prompt2={AAG,Advisory}

Any help with this would be appreciated.

Thanks
Scott
