jQuery not defined

I have searched the forums for this problem and seen several related topics. But none seem to indicate a solution that helps me. I'm using the Twenty Ten 1.2 theme and have created a separate file that is require_once in the functions.php. This file contains the simple shell specified in the Usage for Gform post render documentation (http://www.gravityhelp.com/documentation/page/Gform_post_render) as I just want to see that I'm placing the JavaScript in the correct place. But I get a "jQuery is not defined" error in Firebug. My short code for my first Gravity form is in a page like this [gravityform id=1 name=AskALibrarian ajax=true]. I can see that jQuery version 1.4.4 is loading in the header. I tried changing the jQuery at the start to $ but this produces the same kind of error. FYI, the form loads fine.

Unfortunately, we are developing the new site on a server behind a firewall. So I can't provide a link that will get you to it. Does seeing this code from the head of the page help?

<script type="text/javascript">
// This file is included in the theme's functions.php file.
jQuery(document).bind('gform_post_render', function(){
// code to trigger on AJAX form render
});
</script>
