An action before updating record
Hello everybody,

I wish to know if is there a way to do an "action" just before adding/modifying a record in a table.

Suppose this scenario: user add a record, but after his entries, I have a "Field_C" that must be populated according a complex formula, based on the contents of "Field_A" and "Field_B" (for example).

So, the user input the value for "Field_A" and "Field_B" and press the button Submit. At this point, before updating the record but after submitting by the user I have to calculate the value for "Field_C".

Is it possible to do?

Thank you in advance for any help.
