I want to increase the final price based on the answer to one of the form questions

I am using Jotform as registration tool for our football officiating association. We offer 2 membership dues prices. A lower price ($85) for 1st year officials and a higher price ($165) for returning officials. This year we are requiring that all officials have liability insurance. If they answer "None" to the question of what type of liability insurance they have, we want to increase the total dues by $25 to cover the cost of obtaining group liabilty insurance. In other words if the registrant clicks on "None" in the "Which organization is providing your officiating liability insurance?:" We want the Payment Settings to change to $110 for 1st year officials and $190 for returning officials.

Is that what you're trying to achieve? Additional $25.00 if the user answers "None" to the field question. 

In the demo form, I have used Form Calculation widget to pass the total to the Payment field. The Form Calculation widget calculates the 2 field (Which organization is providing your officiating liability insurance field and OCFOA DUES field).

The None option is equal to 25.

I also set the OCFOA DUES field option calculation values.

The total of the two field using Form Calculation widget. Here's a guide for more information: https://www.jotform.com/help/259-How-to-Perform-Form-Calculation-Using-a-Widget

After that, I pass the Form Calculation total to the Payment field by following this guide: https://www.jotform.com/help/275-How-to-Pass-a-Calculation-to-a-Payment-Field

Please clone my form to further investigate it and if you have questions, please let us know. Thank you.

John, you're awesome, that's exactly what I needed! I had forgotten about the calculation widget. Jotform ROCKS!
