Error Message

[Jim]

I have been working on a query, and everything works fine. I changed one of
the search parameters to include additional information, and now I get an
error message "INVALID ARGUMENT". When I click the HELP button, it tells me
that I am trying to run a dll file. Can anyone tell me what it is really
telling me?

Show us the SQL. Open both queries (what works and what doesn't) in design
view. Next go to View, SQL View and copy and past it here.
