Guys I have a form that uses a simple javascript to get a value from the picklist, then replace the value in an input field so that when submit is clicked, it sends the correct information to the server. My issue is that I had this working and not it isn't for some reason. Maybe one of you can help me see an error I made.

the script:
$(function() {
$("#display_value option").click(function(){


The relevant form data:

<form name="Booking" action="form/capture.php" method="post" accept-charset="utf-8">
<input id="get_value" type="hidden" name="publicid" value="" />
<input type="hidden" name="name" value="Booking"/>

<table width="100%">
<td align="right"><label >Who is your agent?</label></td>
<select name="label:Agent[]" required="true" id="display_value">
<option value="e023f0f7">Please Choose</option>
<option value="ec4d03d7">Philly</option>
<option value="a80bf9d9">Kirk</option>
<option value="96c6e63b">Jonah</option>
<option value="38bc0bcf">Ken</option>

As you can see above, the input "publicid" is supposed to grab the value from the pick-list based on the option chosen. The pick-list is id "display_value" and the input is id "get_value". What am I missing???

If I put the value from the option in the input field (for example "e023f0f7") into the value of the input field (such as value="e023f0f7"), the form saves the information to the correct place so I know that the script is the issue.
