maybe something like this:

Just to make sure I understand why this works... is this a correct
explanation for why ".length" is in there?
If we've found a matching value in another select element, ".length"
returns 1 or greater, so the condition is executed. If no matches, it
returns 0, so the Else condition is executed.
Thanks again,

If no element is found it returns an empty array, which (at least in
Firefox) is not false.
aw, I should read more carefully.
Yes, you're right of course. That was just the explanation why not using
length would be bad. :)
