Addition of sums not supported in TQuery using Paradox 5.x ???

I'm doing a select wherein I add together several SUM(x)'s.  It worked
fine with an ODBC driver, but now using the Paradox [STANDARD] driver, I
get "capability not supported".  Is there another way to do this?  Or,
is there some other setup required?
