    Dynamic Textbox: Request to be able to get a Sum of the inputs

    Asked by Wtfuck on April 21, 2017 at 03:48 AM

    Hello JotTeam

    I would like to have the possibility to calculate each added textbox together.

    If you have a workaround I'm 100% IN

    Ex : Field1+Field2+Field3....=TOTAL

    Unfortunately it is not possible to perform calculation with values that are entered in dynamic fields, like Dynamic Textbox, Configurable list or similar.

    I can only suggest you to use basic field. You can use conditional logic to show another field if previous field is filled.

    Here is my demo form: https://form.jotformpro.com/71102176051947 

    Or you can use Input Table (Matrix) field.

    You would need to write a custom java script code to perform calculation with Dynamic Textbox widget. The widget is loaded inside an iFrame, it might be tricky and you may need to hire a programmer from Upwork or Freelancer to achieve this requirement using the source code.

    Inside of this guide you can find how to get Full source code of your form:

    I have checked with one of my colleagues and theoretically it should be possible, but the iFrame usage of widgets may cause there to be a lot more work.

    This would not be something we can support.
