Gaylen,
You should reassign the controlsource for calculated column. When grid doesn't have a controlsource for a column it picks the next from recordsource.
When assigning calculated fields use the aliases + parentheses. Failing to use parentheses is a common cause of blank column.

thisform.myGrid.Columns(n).Controlsource = ;
"(myTable.Example - myTable.Sales - myTable.Return - myTable.Receipts)"
