    I would like to create a field that adds the total of a PO form with a number entered into another field.  The Form Calculator does not list the PO form total as an available field to choose from.  See image at this link:

    Hello rlalley,

    Unfortunately, we do not have such feature. To achieve your requirement, you will have to download your form's source code and add custom JavaScript to copy the amount from "Purchase Order" tool to another form field.

    Please be noted that if you embed your form with its source code, any changes you make in JotForm editor will not be visible in your web page. You will have to download your form's source code and embed it again. Do get back to us if you want to take the source code route and we will help you with the custom JavaScript. 

    Thank you!
