Hi @b__BiswabhusanD ,

Use below script it will work, your script not working because when you are using clear messages need to remove newValue in script.

function onChange(control, oldValue, newValue, isLoading) {

    if (isLoading) {

        return;

    }

    var locationValue = g_form.getValue('location');

    if (!locationValue) {

        g_form.addErrorMessage('Please select a location.');

    } else {

        g_form.clearMessages();

    }

}

@b__BiswabhusanD 

why not make location variable as mandatory and you won't require any script?

update script as this

function onChange(control, oldValue, newValue, isLoading) {
    if (isLoading) {
        return;
    }

    if (newValue == '') {
        g_form.addErrorMessage('Please select location value');
    } else {
        g_form.clearMessages();
    }
}
