I'm trying to invoke a filter on a TIBOTable. The filter query in question
is a compound statement somewhat similar to this:

aTable.Filter:=(x > Quantity_from_Supplier1+Quantity_from_Supplier2);

When I try to do this, I get a "missing or extra" parenthesis. In SQL I know
I can add this to the where clause and get the correct results so I'm left
wondering if this is an ibo bug :-(

Any suggestions anyone?
