    you can have a total field which calculates price X quantity using JotForm payment tools, you can add products, set the prices and show the calculated total. Check this example using the "Purchase Order" payment tool.(you can achieve the same with other payment tools)


    Please check this user guides:



    Hope it helps

    You can do this using the options in the payment tool.

    Please review this guide How-To-Add-Options-In-The-Payment-Form

    By "calculate total", I think you were referring to "sub-total".


    Hope this help. Inform us you need further assistance.

    I do not seem to be able to get what I want out of thi. I need a purchase
    order form
    (see link http://form.jotformpro.com/form/32332894626964)
    where I input the description, qty, and price and the total is calculated
    as qty * price
    In every example from above emails the line item has a predefined
    description and price. Can I input the price, qty, and line item and
    calculate the total?

    The only fields that have calculation functions are those in the Payment tools. Using the form builder only, you can use the Purchase Order tool that calculates total.

    You can modify/customize the Purchase Order tool using this guide How-To-Add-Options-In-The-Payment-Form


    You will need to use the form's source code to be able to have computed calculation between textbox fields in the form. Similar to this demo form.
