Dear list,
I'm having difficulty trying to 'universalise' a MB program. Part of
the routine performs a query, and then does a calculation on the
selection. However, on some tables the query doesn't return any data,
so there is no selection on which to perform this calculation. Is
there any way to get around this, so the program won't 'trip up' and
crash when nothing is selected?
Many thanks in advance,
Tom
