    How to update a form field value using conditions?

    Asked by bybe2937 on June 11, 2015 at 06:48 PM

    I just had a quick question about a widget that I have not come across yet. I'm trying to create a form that as you put values in it, the values in another box change similar to functions in excel. I really just need to do two simple calculations. Basically the amount of the product is entered and I want have the price right next to it when they enter a value by multiplying that number by the price per unit. If this is something that is possible that would be great. Thanks!

    looks like this "update the form field value" no longer exists in the conditions setup.
