Function to add up three variables and compare to another variable? How?

[Crispywafers]

Hi,

Can someone just tell me if it's possible to create a procedure that
would add up three variables and compare to another variable... and
add the difference or subtract?

We split our tuition into 3 equal payments. Due to rounding sometimes
we manually have to add a dollar or subtract a dollar to the last
tuition payment so that the three tuition payments equal the total
tuition payment.

Because we are trying to use access now to print and track our tuition
payments... I need a way to do this in the VB calculation for the last
trimester payment.

Help?

Public Function getLastTrimester(cTotalDue As Currency, cCurrentPayments As
Currency) AS Currency
getLastTrimester = cTotalDue - cCurrentPayments
End Function

This is far too simple so I suppose I do not understand your question
entirely...
