I see a couple of problems. First up, they're not indenting. The validator is spitting the dummy because of two things, the first is the spurious whitespace before the doctype tag, the second is the title (which it thinks is missing), but the real problem is with the meta tag which isn't properly closed.

But hey, free dinosaur. With hat.
