If the answer is yes, then 3 number fields appear asking how many meals for adults, older children, and younger children. If the registrant checks "yes" to request vegetarian meals but then doesn't modify any of the 3 number fields, I want the form to prompt the registrant to choose a non-zero number in at least 1 of those 3 number fields. So I've created a number field (id 39) in the form (id 12) which totals the 3 number fields, and added the following code to functions.php<br /> <pre><code>add_filter(&quot;gform_field_validation_12_39&quot;, &quot;custom_validation&quot;, 10, 4); function custom_validation($result, $value, $form, $field){ if($result[&quot;is_valid&quot;] &amp;&amp; intval($value) == 0){ $result[&quot;is_valid&quot;] = false; $result[&quot;message&quot;] = &quot;Total vegetarian meals must be greater than zero&quot;; } return $result; }</code></pre> <p>But it doesn't generate an error message if I leave all the 3 number fields as zero. What am I missing? </p>
