A full-feature "calculator" that uses numeric constants and the contents of fields from Act! records to perform simple or complex calculations, and save the results into an Act! field.
Field Calculator can be used either as a trigger or as a custom command. It can reference fields on the current Contact record, the current Group record, and the current Company record. Any combination of fields can be used, along with "plain ol' numbers" to perform mathematical functions, including addition, subtraction, multiplication, division, exponentiation, trig functions and more.
