Try running your HTML thru a validator - fix all reported errors and warnings. Might find it right off :-)

i know there are a quite a few errors on the validation side of things, but will that really make much of a difference?

Try the button in a fresh (empty - no content whatsoever) page to see if it's your button coding or the page you placed it in.

Have you run your url through the url linter tool? [developers.facebook.com...] Sometimes this forces facebook to crawl your site and fix these errors. Other times I've noticed this is just down to allowing time for them to crawl it.

great works a treat, I think it was because I placed the facebook post behind comment post. I have now placed on the pre post also and works well. Thank you. Is there anyway I can add parameters into the message?
