I have a combobox within column2 of a grid; the rowsourcetype is set to SQL statement. The statement is this:
select acctno from glacct into cursor gllookup

As Cetin says, this statement should not be too long at all. Just for grins and giggles, what happens if you set the RowSource up like this:

.RowSourceType = 6
.RowSource = "glacct.acctno"
