    Thank you for contacting us.

    Yes you can.

    Using the Calculation wizard, you can select the fields that are in the calculation, and decide what to do with them to get an output.

    For example, in the Available field, you could select the Calculation wizard and tell it what should be calculated as the result as shown below:

    Here's a test form: http://jotform.com/form/40216778024957

    You can copy it into your Jotform account and take a look.

    Please let us know if this helps.
