Using “Submit” image on multipart form

On a multipart form at http://www.editfast.com/editsub.htm I have a “submit” image at the bottom of the form

which I think is causing problems but I don’t know why. FormMail returns a message “no recipient or an invalid recipient” but there is a recipient on the form

and the same recipient appears in the @recipients in FormMail.pl
@recipients = (‘^editorial@editfast.com’,’^jeditorial@editfast.com’,’^jobs@editfast.com’,’^jjobs@editfast.com’,’^free-estimate@editfast.com’,’^jfree-estimate@editfast.com’,’^price-list@editfast.com’,’^jprice-list@editfast.com’);

Can anyone spot my error. Your help is appreciated.
