    How to do calculation in my form?

    Asked by daothitam92 on December 06, 2016 at 07:56 AM

    how to do that calculation? I tried many times but it didnt work.

    For example I have a field of DURATION (drop-down)with 3 options: "1 month", "2 months","3 months".

    I have the 2nd field which is FEE.

    I want when I pick "1 month" in DURATION then a value of "200$" will appear in the field of FEE.

    What should I do?

    I have understood your issue and I have created an example form for you. Please check the following example form link: https://form.jotform.com/63403407296960

    Please check the following steps below after creating a drop down list and a text box:

    1. First of all, open the configurations of the drop down list and click the Surveying tab. You need to enter the calculation values. You should separate each value with a new line as you can see the following screenshot:

    After saving the changes, each drop down list item will have the following calculation values:

    empty -> 0

    month 1 -> 100$

    month 2 -> 200$ 

    month 3 -> 300$

    2. You need to set Conditions to copy the value of drop down list and make it appear in the text box field as you can the following screenshot:

    3. Set the conditions as you can see the screenshot below:

    Save your conditions and your form.

    Please try this. If you need further assistance, let us know.
