Referer doesn't work

On my webpage (www.webone.com.au/~bwhite/index.html) I show the XHTML1.1 
icon with an appropriate link to "http://validator.w3.org/check/referer" 
as suggested on the validation page.

However, when I click on the link, it attempts to validate the validate 
page rather than my own page, and shows an error.

My page validates separately as XHTML1.1.
