There are 6 errors listed by the W3C HTML Validator, for the same line of code, preventing one of my web pages from validating.

This is a bogus message as the code snippets listed by the Validator are Javascripts that do not appear anywhere on my page! (Though, I do have two javascripts: one is Google's own Analytics script and the other is the script given by Add-This for tracking Shares.)
When I used the email link beside the offending code to send here, this is what appears in my email message:

   [ Validating http://www.kerrie-redgate.com/purpose.html Error [127]: "required attribute X not specified" ]

It seems the Validator is displaying something completely different to the actual errors.

I don't understand this and can't fix it at my end.

Thank you.
