<a target="_blank" href="http://www.facebook.com/profile.php?id=".<?=$Facebook?>________________
<img src="image/facebook_account.png" border="0" /> 
</td>

I spy with my little eye an unclosed HTML tag.

EDIT: Exaggerated for effect.

This wrong as well?

id=".<?=$Facebook?>

Should be:

id=<?=$Facebook?>">

Added in the closing > as well

[StarLion]

You added the closing >, and took away the opening " !

id="<?=$Facebook?>">

PS: I wouldn't personally use shorttags, but its still valid.
