calculation in fields

[danacol]

Hello,

Wondering if is possible to apply calculation proprieties to form fields.
for example, having two fields, field A and field B, is it possible to get in a third field the A+B result?

thanks

First a thing that you may already know... but many people need to be told...

It is a bad idea to fill a field in a TABLE (using the term in the narrow, database, sense) with the result of the sort of calculation you are talking about.

However it is easy and common to display the result of such a calculation on a form.

See....

thanks for the link.
It shows how to get calculations with queries, but would it be possible also using macros?

PS why is a bad idea to fill in fields with calculations??

Thanks
