When you get the Nesting Error, check what value is in orders.printed (make sure it's a logical, and what you get from len(alltrim(orders.po)) (make sure it's numeric. I've seen nesting errors in a SCAN statement when you would normally expect something like "Data type mismatch".

The second problem sounds similar. There's something wrong with your Orders table in some cases.
