You've only shown us one of the User elements. The others must be different
in some way if they are coming out differently, but we can only guess at
how. You also haven't shown us the key definitions, or the namespace
declarations.

I have a suspicion that the problem is because you are assuming that the
key() function is operating locally to the current User, when in fact it is
operating across the whole document.

One suggestion: use CSS for the styling. Generate HTML elements that refer
to a CSS class, and then adjust the appearance using the CSS class
definitions. If you can't do that, at least get rid of all the styling
clutter to produce a cut-down stylesheet that illustrates your coding
problem. Sometimes when you cut it down to the bare bones, the error stares
at you in the face.
