'Invalid' validator response but no errors in output. Please help!

Hi please help! I am trying to validate
www.thelinemarkers.com.au/1index.html . I had a valid response from the
server so I put a link to your website, and now the link says my site is
invalid, but it shows no errors in the output. Even if I tick the output
box still no output. Im not sure what to fix? Please if you can help me
ill make a donation. Thanks..
