Simple Invoices - Forum

Ive noticed that in Safari running on a windows box, all settings etc works without a hitch and I can see the Payments menu in Money section.
But its not working in IE8 im seeing a js error shown below and im not a js wiz. so perhaps someone else can let me know whats wrong.

The page link is this -> http://localhost/simpleinvoices/index.php?module=payments&view=manage and the error shown below is for IE8
