Calculated field not appearing in Table

Hi there,

I have the following fields:
FY07/08, FY08/09, FY09/10 and Total_Budget. The "Total_Budget" field is
simply a calculation of the other 3 (=[FY07/08]+[FY08/09]+[FY09/10]) and does
not have a control source so does not show up on the table, but works fine in
the form.
I need to be able to add this field so that it shows up on the table (under
"Total_Budget") too.
Any support would be much appreciated.

Thanks

There is no need for that.

Create a query based on your table and put the calculation into it. Use
this query in all theses cases where you need the calculated field.

Calculations should not be stored in a table. There is no need to as you can
always calculate them on the fly using forms, queries or reports.

Storing derived data such as this in your table accomplishes
three things: it wastes disk space; it wastes time (almost
any calculation will be MUCH faster than a disk fetch); and
most importantly, it risks data corruption. If one of the
underlying fields is subsequently edited, you will have data
in your table WHICH IS WRONG, and no automatic way to detect
that fact.

Just redo the calculation whenever you need it, either as a
calculated field in a Query or just as you're now doing it -
in the control source of a Form or a Report textbox.
