Parametervalues in a Child Command

My problem is: How do I put values into parameterfields of an sql-statement in a child command in a Data Environment at run-time.

I'm trying to fight my way through my first attempt with DataEnvironment and a Data Report. I'm using Jet 4.0.

In the DataEnvironment I have created a command called 'Group' with a child command called 'Detail' referring two different tables.

In both commands I have typed in Select-statements with questionmarks (?) in the Where-clauses.

At run-time I can assign values to the 'Group'-command by this line of code: Dataenvironment1.Group (intGroupId)

How do I do something similar with parameters for my child-command 'Detail'?

(Everything works perfect if I have hard-coded values in my select-statement's.)
