Result not stored in the table

I modified the customer template database that available from Microsoft
Online as per my requirement.
in the table case. I add new fields, 1st [Price / Qauntity], 2nd [Qauntity],
3rd [Total Price].
now in the case detail form I add those fields, but in the [Total Price] I
made formula that will calculate [Price / Qauntity]*[Qauntity]. but I
surprised there is no result in the case table

Regards

Surprised? The method for getting a control to store its value in a field
is to place the name of the field in the control's ControlSource property.
You have not done that. You have an expression in there. A control is
either bound to a field OR contains an expression. It cannot do both.

The good news is that proper database design dictates that you should not be
storing that value in your table anyway. Just remove that field from your
table and any place you need to see that value use the expression you are
using now in your form.

Tables should contain raw data only, not data that can be derived from other
data. That is the job of queries, forms, and reports to calculate in real
time as needed. That way there is never any doubt as to its correctness.
