Yeah, this is part of what's tricky about validating HTML or CSS, or
debugging in general -- sometimes the error message you get is a red
herring - and the real problem is some distance before, or some distance
after what it *says* is the problem.

Tricky to debug, but once you get used to it that kind of debugging
instinct will help you code in pretty much any language.
