You have a < where you shouldn't have one. Most likely because you have PHP tags when you've placed the PHP within an existing code block. If the code is already within a PHP tag and you try opening another you'll get this error.

I have followed your steps above, and replaced the form ID and field IS's with the correct ones from our form. For some reason I keep getting an error: Parse error: syntax error, unexpected '<' in /home/content/58/7982758/html/wp-content/themes/twentyten/functions.php on line 518 Is there something Im not doing correctly to get this functioning properly?

However, I want to populate the second drop down with another list based on the previous drop down value. I can do this using ajax base on the previous drop down value I can query the database and return another drop down list, but I am not sure how to dynamically populate the list into the second drop down.

I understand the concept of jQuery, but I am taking it on as a new venture. I know where to put the code but I am not sure what the syntax is for communicating with a form and a field on the form? My current code looks like this : <pre><code>add_filter("gform_pre_render_11", monitor_dropdown); function monitor_dropdown($form){ ?> <script type="text/javascript"> jQuery(document).ready(function(){ jQuery('#input_3').bind('onchange', function () { alert("test"); }); }); </script> <?php return $form; }</code></pre> I think once I have the basics I will be able to figure out the rest. vixvii on "dynamically populate fields based on drop down selection" https://legacy.forums.gravityhelp.com/topic/dynamically-populate-fields-based-on-drop-down-selection#post-28191 Mon, 20 Jun 2011 14:57:33 +0000 vixvii 28191@https://legacy.forums.gravityhelp.com/ Thanks again Carl! jQuery makes complete sense Carl Hancock on "dynamically populate fields based on drop down selection" https://legacy.forums.gravityhelp.com/topic/dynamically-populate-fields-based-on-drop-down-selection#post-28189 Mon, 20 Jun 2011 14:52:58 +0000 Carl Hancock 28189@https://legacy.forums.gravityhelp.com/ You could only do this with custom jQuery. You'd have to write custom jQuery and attach it to the drop down field and then use jQuery to populate the fields with the data. There is no hook on drop downs because no PHP is triggered by a drop down so you have to do it using jQuery. To execute code when the form is submitted you can use the gform_pre_submission hook or the gform_post_submission hook. Both will do the trick.
