I'm creating some custom fields for my Companies, and I'm wondering if it's possible to specify that two fields should be added together to make a third field...
IE I have one field that is, say, "Monthly Fee" and a second field that says "Annual Fee" which would simply be "Monthly Fee * 12" for display purposes.
I would also like to specify, say, in a text field, a default value that would remain in the event that field was not specified.
Thanks in advance.
