Hi @Saib1 Please try below.

function onSubmit() {
    var groupMembers = g_form.getValue('add_group_members'); 
    
    if (groupMembers) {
        var memberCount = groupMembers.split(',').length;

        if (memberCount < 20) { /
            alert('You must select at least 20 members to add to the group.');
            return false; 
        }
    } else {
        alert('No group members selected. You must select at least 20 members to proceed.');
        return false; 
    }
    
    return true; 
}
