If you don't need to store the information, then use a variable. As long as there are no serious processing overheads involved with calculating the value.

bbrown

Create a function, on the table, that calculates and returns the value required. You can then use the function as the source expression for a textbox etc.

You do not even need a variable or function, if the value is caculated from 2 fields or values, then you can just add a textbox.

For the Finance Charge Memo Line and a text box where the sourceExp = TODAY - "Due Date"

Same can be done for Decimal Fields for a VAT Amount you could put, SourceExp = "Amt. Inc. VAT" - Amount
