    How Can I Create Multiple Calculations using Multiple Fields?

    Asked by theorganicninja on March 01, 2015 at 07:45 PM


    How can I use the calculation widget to create the following effect on my form:

    Product Field:  <customer inputs number of products desired, ex. "4">

    Product Cost Field:  <populates/displays cost of item given above quantity, ex. 4 x $20, displays "$80">

    Total Cost Calculation:  <displays all calculations from all Product Cost Fields, ex. "$10000000">


    Thank you for your help and patience!  I'm still finding my way through Jotform.

    Create a form as follows : 

    where Product A and Product B are the two products.Product A cost ,Product B cost and Total Product Cost are the three form calculation widgets used . 

    After inserting form calculation widget in your form , calculation wizard will open . Add the fields as follow :

    Similarly, do it for Product B.

     After getting product costs for both products, for getting the total quantity of both products , we need to add the individual product costs to get the final outcome.


    Thanks ,
