    I need calculation tools

    Asked by hventry on September 10, 2012 at 10:20 PM

    Several Number entries need to automatically combine to yeald an amount due.  Example:

    Tuition: $50

    Discount: $10

    Book: $6

    Amount Due: $46

    where Amount Due = Tuition - Discount + Book (This rule needs to be created in the form.)
