The validator seems to indicate the BR is in the wrong place, the other errors are more clear cut your ";" should not be there at all, no idea why you have it there.

the <u> tag is not part of XHTML standard, you should use CSS to underline instead.

Same goes for TD, width should be supplied by css, and your font statement should be replaced with a better css substitute.
