Custom calculation for field using other field values

    I’d like to include a field in the form, the value of which will be a custom calculation, based on values of other fields in the form. Ultimately, I’ll probably want this instead to be a popup when the user submits the form, but for now it can be a hidden field that appears once the user has filled out all the fields (all are required).

    Is this fairly doable? I’ve coded quite a bit, though am a bit rusty, and have not done custom coding for plugins. If you could point me in the right direction, hopefully I can take it from there.

    Thanks!
    Gary

    You would want to add some javascript to your form, which can by done easily:
    – add a note element to the end of the form
    – give it a blank label
    – check the ‘HTML’ box.

    The javascript functions to access the form’s DOM objects are described here.
