Reusing parameters in a subreport.

Is it possible to reuse parameters from a primary query to trigger the query in a subreport?

My primary report does totals sold grouped by salesman code, and now we need grand totals per salesmanin the report footer.

So what I did was create a subreport that gives me exactly what I need. Now for my problem. We use the visual basic ActiveX control for our users to query the database for the report.

It was fine before since all the user had to do was enter a from_date, to_date, and a state parameter and the report would do it's thing. Now with the subreport it asks for...

from_date
to_date
state
from_date (SalesManTotals)
to_date (SalesManTotals)
state (SalesManTotals)

So our users are forced to enter the same parameters twice. Once from the VB interface, and then a second time from a Crystal Reports box requesting the same parameters for the subreport.

How can I tell the report to use the first set of parameters for both reports without being requested to enter them a second time for the subreport?Try linking those parameter fields to the field in the subreport that contains that data
