You can't use calculated fields in a table. Create a form for data entry
and then a query to perform the calculation, or this can be done direcly in
the form.

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.

To create the field in a Query, create a new Query based on your
table. Type the expression in a vacant Field cell in the query grid:

Total: [Price1] + [Tax]
