    I am unable to get to Conditional Logic to work for a simple calulation.

    Asked by belmontjot on May 03, 2016 at 11:06 AM

    On the form (URL below), there is a "Donation" field, and an "Additional Donation" field. I want to add those fields, and output the total into the"Total Donation" field. I have looked at the online videos, and user guide regarding Calculation, but I can't seem to make it work. I have also tried the Form Calculation Widget, which does a calculation, but I can't output the total to the "Total Donation" field.

    Can you provide further instructions?

    I see that you are having some issues with getting two donation fields to combine and sent into your total donation field as the final prepared payment.

    This problem stems from the fact that you were initially only using updated field calculations to carry over the data and that won't work in this particular instance because all that does is copies it there since it wasn't fully calculating it.

    Instead please do what's suggested in this guide here https://www.jotform.com/help/275-How-to-pass-a-calculation-to-a-payment-field which should shed a lot of light and clarify how to set this up more appropriately.

    You basically need to add a form calculation widget then you can hide that field on your form.


    At this point you can then also now go back into your payment integration and in the donation option the feature to get the total of the two donations fields will now appear to make it work. :)

    Here's an updated version of your form https://form.jotform.com/61235000605944 I made with this fix applied for you. Feel free to clone it and look at what I did to figure it out more if that helps.

    I'm glad to hear that you have already managed to make the form work.

    Now regarding the cloning of forms, what my colleague meant is that you can clone the form that he has, you can do that by following this guide: https://www.jotform.com/help/42-How-to-Clone-an-Existing-Form-from-a-URL 

    I hope that helps. Feel free to drop by here in the forum if you needed any assistance again.
