The Balance Calculator can be used for complex balance calculations.
It uses formulas and literal string replacer values to determine what
amount should be charged.
From the Tools
menu, select Balance Calculator.
The Balance Calculator page appears.
In the
Final Balance field, enter in a formula to calculate the desired
balance. If you have collection grids set up, a formula field appears
for each grid on the form. To use the total value of the collection
grid in the final balance, create a formula specific to that grid
to tell the form how to determine its balance. Example
