My data shows on input but not in reports

[Guest]

On my data input form I have the total price calculated from the item prices.
When I look at the report the total price shows $0.00, the form shows the
real dollar ammount but the reort does not. I have looked at the Table where
the data should be and everything but the total price is being shown.

Don't store the total price in your table AT ALL.

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.
