    How can I make a form to provide a predetermined price when the user submits 2 dimensions?

    Asked by Andy on March 05, 2017 at 09:14 AM

    I run a window blinds business. I am looking to sell my blinds on line.

    I want to produce a form that when the customer enters the width and drop of the blind, a pre determined price is produced. A third field may be required, ie. width; drop and thickness of blind slat.

    How you can help

    Perhaps you can give us a formula and we'll give a sample on how it should print results.

    I am asking your advise on how to do it or if it can me done with a jotform.

    I have price lists on excel, in tables with the width on the horizontal axis and the blind drop on the vertical axis. What I need to know is how can these prices be picked up when a customer puts width and drop into boxes on the form.

    You can set this up by using conditions in JotForm and/or using Calculation widget. Condition setup can be found in Form Builder form in Settings > Conditions tab. In your case, we will be using the Update/Calculate Field condition.


    Here is a sample form that I have created: https://form.jotform.com/70653620412952. In my sample form, I have set the following conditions:

    For more information about conditions, you can check this article: Smart Forms Using Conditional Logic. On the sample form, when I input 5 in Width (cm) and 5 in Drop (cm) the price displayed is $50.

    And when I input 10 in Width (cm) and 5 in Drop (cm) the price displayed is $100.


    You can also clone the sample form that I have created to have a closer look on the setup. To clone form, just follow the instructions provided How to Clone an Existing Form from a URL.


    Do let us know if you need further assistance.
