Reporting action with a parameter

Hi,

I am having an issue setting up a reporting action with a parameter. The report I am trying open is non-cube based database report. I tried a few syntax variations for the parameter value such as:

UrlEscapeFragment( [Dimension].[Attribute].CurrentMember.Name)
UrlEscapeFragment( [Dimension].[Attribute].CurrentMember)
UrlEscapeFragment( [Dimension].[Attribute].CurrentMember.Value)
UrlEscapeFragment( [Dimension].[Attribute].CurrentMember.UniqueName)

But non of them seems to work.

The action disappears ones I set theparameter.

What am I doing wrong?

Thank,

Sasha
