ack, just so no to the unnecessary use of the eval() method.  bracket
notation is your friend and should be used whenever possible.

document.f.elements[es[i]].disabled = true;

there's absolutely no harm in nesting something that's using bracket
notation within another bracket notation.  however, if that makes you
squeamish, then you could do it like this:

currentElm = es[i];
document.f.elements[currentElm].disabled = true;

the use of the power-hungry eval() method chaps my hide whenever i see it.
maybe i'll get around to writing a rant, errr, i mean an article for the
site one of these days.

good luck,
