Well, I got the moment to take a peek at it.

In findCounty.php, change line 11 from:

<select name="county" onchange="getCity(<?=$state?>,this.value)">


<select name="county" onchange="getCity(<?php echo($country)?>, <?php
echo($state)?>, this.value)">

The Javascript function was expecting three variables, but your script
was only echoing out two. So, when you would select an element,
country was being passed as "undefined".

As a neat little trick, when you have issues like this, I usually pop
open Chrome's development window and see what the request was. After
that, it was a matter of tracking down where the Javascript was being
placed on the page from.

Thanks :). It came to me in a moment of genius (I think an hour
earlier I had just finished surfing the bacula website, too).

Unfortunately (to some, who seem rather disappointed I'm not a cartoon
character), I'm not gaunt. I'm a tank of sexiness.
