I followed this code example in the documentation and haven't been able to get it to work correctly (it returns an error no matter what). <a href="http://www.gravityhelp.com/documentation/page/Gform_field_validation" rel="nofollow">http://www.gravityhelp.com/documentation/page/Gform_field_validation</a></p> <p>Here is an example where we need to have a minimum donation amount of $3,000: <a href="http://templedavid.org/jason-z-edelstein-endowment-fund-bricks/" rel="nofollow">http://templedavid.org/jason-z-edelstein-endowment-fund-bricks/</a></p> <p>My code in functions.php:</p> <pre><code>add_filter(&quot;gform_field_validation_12_1&quot;, &quot;custom_validation3&quot;, 10, 4); function custom_validation3($result, $value, $form, $field){ if($result[&quot;is_valid&quot;] &amp;&amp; intval($value) &lt; 3000){ $result[&quot;is_valid&quot;] = false; $result[&quot;message&quot;] = &quot;You must donate at least $3,000 to be eligible for a brick.&quot;; } return $result; }</code></pre> <p>Any ideas on how I can make this work? Maybe it has something to do with the field being a dollar amount?</p> <p>Thanks! </p>
