I have created a query for Product Total Cost in my DB. After I create the query and I try to choose the field from my field list it is not showing up there. I have several of these in another DB and they work just fine. I even went and re created these in my other DB and it still works fine. But in this DB I can not get this one to show up in my list in tables or field list. I have also run compact and repair feature couple of times.
