frm_update_entry hook not working - version 2.03.04 pro

I have the following code in my functions.php in my theme folder.  The function never gets called.  The frm_update_entry hook isn't working for me.  I am on version 2.03.04 pro.  The frm_email_message hook works fine though.  Why isn't frm_update_entry working and how can I get it to work?

function ga_save_form_values($values)
{
   mail('<my email address here>','form values', var_export($values,1));
   exit;
}

add_filter('frm_update_entry', 'ga_save_form_values');
