    Hi! Need to have a checkbox subtract a text field value from the grand total of a calculation.


      When a checkbox is activated "GST Exempt", I would like the GST text field value subtracted from the Total of a sum of fees added together.

      Is this possible? I'm assuming the calculation would have to be be applied to the "Total" text field? Thanks!
