    How to multiply value by quantity and sent to total box

    Asked by kitekidsuk on December 31, 2014 at 12:35 PM


    It's very simple I'm sure, but have been trying for hours and pulling my hair out!

    I have three products (for now). I want user to select types they require, then the quantities for each, then for the total price to show in 'Total all' box. 




    Any ideas where I'm going wrong??? Thanks so much

    It's ok - Ive done it at last. I thought you could use the 'calculation value' from the properties of a dropdown for the price of something, but instead I manually multiplied the total quantity selected by an inputted price into the calculation tool.

    Hi Jenny,

    We apologize for the delayed response.

    I checked your jotform http://www.jotformeu.com/form/43644735613356 and I can see that it is not calculation base on the selection values correctly.

    I suggest checking this user guide on how to do it correctly

    1. -How-to-Assign-Calculation-Value


    2. Then use Calculation Widget to calculate total. -How-to-perform-calculation-in-the-form


    if you want to use Payment tool for total, you can also do that.

    guide: -How-to-pass-a-calculation-to-a-payment-field


    You can test my demo jotform http://www.jotformpro.com/form/43646667395975 to see how it works.

    Hope this help. Let us know if you need further assistance.

    Hi there - your example didnt seem to work either - yours just seemed to add up the quantities - not the values? ie 10 units plus 10 units = 20. I wanted to add up the prices of the quantities. Anyway, I think you looked at an old one - my new working one is at:



    Thanks for your help anyway.
