    Is it possible to build data validation into a form?

    Asked by William Rowan  on February 25, 2015 at 10:24 AM

    For example, if the form asks for a total number of participants, and then asks for a breakdown by male and female, is it possible to generate an error or warning that the total number of male and females is greater (or less) than the total number of participants?

    Thanks,

    William

    thanks then and OR

    Hi William,

    If you would like to perform conditional logic like "if number of males is greater than females then...", yes it is possible. You can find more about it here: http://www.jotform.com/help/57-Smart-Forms-Using-Conditional-Logic. You can show or hide a "Text" field that will act as an error message, when the condition is met or not, you may also need to use the Form Calculation widget to get the total number of males and females then compare it to the total number of participants that you have.

    Just make sure that the input fields are a number type field so that you can compare values.

    Do let us know if you need more assistance on this.

    Thank you.
