Can calculated fields in forms be saved to a table?

[RWagner]

The form Im creating has three fields that need to be calculated to get the
value that belongs in the fourth field. I created a calculated field usinig
the text box command and have the correct results, but how can that result be
placed it the proper field of the table?

A calculated result should only be saved to the table if there are good
reasons why it should sometimes be different than the calculation.

For an explanation of when and how, see:
