What the heck is going on? Chrome is giving "Uncaught SyntaxError: Unexpected token ," : <p>In chrome the following code is giving me an error on some pages, but not others...</p>

<pre><code>$.ajax({
    url : '/package-assignments/add.json',
    method : 'POST',
    data : {
        event_id : ,
        package_id : $(this).data('package').id,
        price : $(this).data('package').price,
        deposit : $(this).data('package').deposit
    }
});
</code></pre>

<p>For the life of me I can't figure out what is going on. the area red underlined in chrome editor tools is "e-assignments/add.json'," which makes even less sense, it starts mid string on an arbitrary letter 'e' and continues to end of the string...</p>

<p>When I remove the string after url and replace it with null the error stays the same but shows to be after "$.ajax({" which also... makes no freaking sense...</p>
