I think we have a symantical problem here. The table is buffered, yes, but is it row buffered or table buffered. If row buffered, you are going to have a problem with CALCULATE or any other command that traverses rows as VFP will automatically tried to commit the row buffer. If table buffered, you don't have a problem: Just CALCULATES SUM(numberfield).
