How to display an error message when condition(s) are no me

[ID NOBLE]

Please I have a requirement to display an error message "Must provide a reason(s) for your selection".

We have a variable of type "SELECT BOX" with options: True, False, Unknown. So, when a user select "False" from these options, the above error message (in red color) must automatically display to users. Please how do I do this?

Thanks.

Hi @ID NOBLE 

As requested by @AshishKM , you need to provide more details so that we can assist you further. Although, you can refer below reference example in which I have made use of a UI Policy to set field message on selection of a particular choice ( in your case, false) in a catalog item.

Thanks and Regards

@Amit Verma,

Thank you, when I used this method, the error message displayed, but I was still able to submit the form which we don't want. Please what more should I add to make the user(s) unable to submit the form unless they meet the specified condition?

I really appreciate your support.

You can make use of an On-Submit Catalog Client Script. Please refer below screenshots :

function onSubmit() {
    var userChoice = g_form.getValue('user_choice'); // Please replace with your catalog variable
    if (userChoice == 'false') {
        g_form.addErrorMessage('Please provide a reason for your selection before submitting');
        return false;
    }
}
