If you have made a copy of an existing Invoice Style and want to edit it, you may do so. It is NOT recommended that you edit any Invoice Style provided by Orion. You should make a copy first.  You may examine the Pay this Amount Field calculation by right clicking on the field and choosing Calculations. This will display the calculations screen with the variables that are included in the value that will print for the Pay This Amount Field.

If you delete or add a variable to a calculation, you will need to Right click, select Compile, and make sure that you do not have any errors in your calculation. In order for the calculations to work correctly on the invoice format, you cannot have any errors after you do the compile step.

Keep in mind if you do change the calculation for the Pay this Amount field or any other calculation fields in the total section of the invoice, you may produce odd or incorrect results.  For instance, if you remove the Previous Balance field from the Invoice Style and from the calculation for Pay this Amount, your invoice total due will not match what is on the ledger on Matter Status if there is a previous balance showing.

Editing or troubleshooting Invoice Format calculations on firm created custom invoice formats or on standard invoice formats that have been altered by the firm is considered a billable service by Orion.
