    Can I keep the leading zeros of numbers in a text field?

    Asked by pwregalado on January 06, 2017 at 05:28 PM

    I'm working with form that needs to sort through a bunch of different combinations of checkboxes, and to simplify the process I'm converting the combinations to a binary form (eg, 1001101, 0001101, etc). The only issue is when I pass Calculation Values from the checkboxes to a Textbox Field, it condenses the numbers that begin with 0. Is there any way to force it to keep the zeros at the beginning?

    Thank you!

    You can try to add a Form Calculation widget and directly transfer the value of the Options checkbox to the calculation widget as text so you can have the 000's displayed on the field. For more information about calculation widget, you can check this article: How to Perform Form Calculation Using a Widget.

    Ensure that the added field in the calculation widget is set to A-Z as shown above so the value will be inserted as text. Here is how the field will look like in your form:

    However, this method will not work when you select multiple options. It will display the values as comma delimited as shown below.

    As a workaround, you can try to ad different textbox for the value of the different options. The value for the checkbox will be 0 or 1 only. Here is a sample form that you can check to see if this is what you are looking for: https://form.jotform.com/70058958545972


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