    How to use calculation with Inventory widget?

    Asked by sloughbottom on July 25, 2016 at 04:36 PM

    I used the calculate widget with radio buttons before, and all you had to do was go into the settings and enter the value of each line. There doesn't seem to be this option with the inventory widget.

    How can I make each item calculate correctly into my "total" box at the bottom?

    -- I wish there was a "how to" article for each widget, so we didn't have to flood the forum with questions that are quite easily answered with a typical explanation.

    Since the inventory widget sends the number of items selected to the calculation, it is required to calculate the value manually with the selected inventory value. I have cloned your JotForm to my account and made the changes below to the calculation.

    This calculation displays the final amount after adding all the values from each inventory widget.

    Please check the cloned form below:


    You may also clone this form to your account to see how the calculation is set.

    We'll try to publish the guide to help using the calculations with the Inventory widget.

    Thank you!

    oooooh that is exactly what I thought I should do, but I missed the * symbols between the items and I put the brackets in all the wrong places. Thank you so much for the enlightment. I did it and I believe it is working, and it is quite easy to edit as well. Thanks again!

    You're welcome. 

    It seems that your number of a quantity that can be selected is set to zero. Please check that. Otherwise, users will get the following error in the widget:

    This widget doesn't work. I've spent hours inputting information into the widget only to have it erased when I return to the website. I hit finish on the widget and I make sure the jotform finishes saving. No matter what I do everything is erased. Is there another widget or do I have to give up on jotform?

    So, the jotform widget I was using has been updates so now whenever I save the calculations I've entered. it saves and refreshes the whole page. I have 15 of these calculation sections to input and it's taking me an hour to do one.
