 * Hi,
 * I get the error message:
    Uncaught TypeError: Cannot call method ‘apply’ of undefined
 * The plugin works fine, but I think the error message is stopping another plugin
   from working.
 * Regards
    Ian

 * Thanks for the reply. Is it possible for me to send you the site by email? I’d
   prefer not to put a link on here.
