Calculation resulting from checkbox selection in a PDF
I am very new at creating custom calculation scripts, and I don't know how to do the following:
I need to calulate the total of all fees associated with the boxes checked:

The checkboxes are titled Checkbox1, Checkbox2, etc.
The exception is the custom fee boxes, that's where I'm getting stuck. If those checkboxes are clicked, they will enter a dollar amount in the FEE1-FEE3 fields.
The Total will be calculated in a "Total Fees" field.
Is this possible?
Thank you VERY much for your help!
