    How can I get the "other" field in the Radio Buttons options to be validated as a number for the calculation widget

    Asked by thescenedramaworks on August 10, 2014 at 04:37 PM

    How can I get the "other" field in the Radio Buttons options to be a numeric field?

    This is a re-post of a comment on How to Perform Form Calculation Using a Widget

    Did you mean that you are trying to set the " Other " option for the radio to a numeric validation? Or?

    Yes. I would like to allow numeric entry in the other field so that I can use the result in a calculation. All of the radio button options are numeric and works fine in the calculation. But the "Other" field appear to be set to text or perhaps alpha numeric. When I put an number in the "Other" field it does not calculate. Is it possible? Any help would be appreciated.

    I'm afraid you cannot currently apply numeric validation for that field yet - I doubt that validation is what is causing the calculation widget not to read it though...

    In any case, our developers are better placed to advice about this - I have forwarded your request, and we shall update you on this thread -

    Thank you for your patience.

    Thank you for your quick response - your illustration is exactly what I'm trying to do. I'd love to know if your developers are able to solve this. As a practical matter, this type of functionality has profound implications. 

    For me, it relates to charitable donations where each of the options in the radio button is a number. The results of the calculations will then be passed through to the currency field of the form so that payments can be processed via PayPal. So as you can imagine, this is tremendously useful. I look forward to finding out what your developers can do. Thanks again
