Can I also assume that you have either wrapped your listener function
in a dom:loaded listener, or have placed it inside a script block
BELOW the ajzip element?
That's another reason why it might not work in some cases, although I
would be surprised if it worked in any browser if the listener was
defined in the DOM before the element it was supposed to listen to.

Walter you made me doubt myself... LOL I've been integrating this
new code with the old form and the id's are different in the old
form but I had made those changes.
Event.observe('ajzip', 'keyup', cities);
<label class='column' id='labzip' for='ajzip'>5 Digit Zip:</
label><input type='text' name='zip' size='5' maxlength='5'
id='ajzip' class='required validate-digits'>

Does your field have the ID attribute set to 'zip'? If it's working
in IE, that's a strong bet that it doesn't, but that it does have
the name set to 'zip'. Element.getValue() and $F() need a valid
(properly-formed and unique on the page) ID for their magic to
happen. If you can't add an ID to the input, you can pass a more
elaborate selector like document.forms[0].zip (without surrounding
quotes, naturally) into the function. $() will work from an object
or an ID, but it won't work with just a name, except in IE, which
has a serious bug in that corner.

In Firefox 3.6.16
I have an Event.observe('ajzip', 'keyup', cities); and the first
line of which tests to see if I have 5 digits entered in the zip
code field and if so it makes an ajax call... works great in IE.
When I press and release a key, my function "cities" gets called, it
tests the length of zip and then jumps into prototype.js on line
4064 where it attempts to execute the following lines:
1) getValue: function(element) {
2) element = $(element);
3) var method = element.tagName.toLowerCase();
4) return Form.Element.Serializers[method](element);
When line 1 gets called, element is set to "zip"; line 2 returns
null and line 3 throws an "Element is null" error!
Like I said, this all works fine in IE. Any ideas?
