    How can I prevent users to submit my form if percentages is not equal to 100%?

    Asked by switchboardllcnow on August 24, 2015 at 11:28 AM

    Reference page 6 of this form: http://www.jotform.com//?formID=52245302899965

    In this form, it's required for a user to list business owners and the percentage of the business each member owns. Is there a way to build/structure this field so that the user can't proceed until the list of percentages equals exactly 100%?

    In an ideal world, this field would have two columns: One for the Business Owner/Member name, one for the percentage of ownership. Then, the second column's values would have to add up to 100%. Is any/all of this possible?

    Hope this makes sense. Thanks!

    Thank you for contacting us. 

    Instead of text area field on page 6 you can set 3 text box fields and 3 number fields. Than you can add Form calculator widget and calculate numbers from Number fields.

    http://www.jotform.com/help/259-How-to-perform-calculation-in-the-form

    Then you need to set conditional logic to Hide/Show page break. You would need to set conditional logic to show page break field only if calculation fields is equal to 100. 

    Here is my demo form: http://form.jotformpro.com/form/52355387628970? 

    Please see changes I made on page 6 and if that is what you want to achieve.

    Feel free to clone my form to your account if you want to take a closer look. 

    Hope this will help. Let us know if you need further assistance.

    Is there any way to disable/hide just the "Next" button until the 100% calculation is met, rather than removing the entire page break? I want to preserve the user's ability to go back if they need to. 

    Thanks!

    Yes, we can achieve this by adding custom CSS, which will depend on the Conditions you have already set in place. We can add this CSS to your form:

    #cid_33.form-field-hidden { display: block !important; }
    #cid_33.form-field-hidden .form-pagebreak-next-container { display: none; }

    What the code does is, when the Page Break on that specific page is conditionally hidden, this code forces it to show, but hides the Next button.

    We can add the code by opening the Designer (Setup & Embed > Designer), and pasting the code into the textbox under the CSS tab.

    Here is a demo form where you can see this code in action:

    Please let us know if you hit any snags along the way, and we will be happy to help.
