Validation fancybox e jquery ui

[esacerbare]

I am using fancybox:
http://fancybox.net/
and jquery:
http://jqueryui.com/
But I have a big problem.

They are not validate on w3.org while all my pages of my web site respect there rules.

I have a very old version of fancybox that it is validate so I am thinking that I can use that but for jquery I don't know like I can do... :(

I look for a either css or flash elegant grey calendar but I don't find one.

I am very sad for this, I need for a big help this time... :(

Thanks :(

As per my test to validate the http://fancybox.net/, here is the 1 error : there is no attribute "rel"
if you are getting similar error then in the JS change the rel to a class or id.
for clear view on your problem plz supply the Website URL which need to be validated.
