Hello Bryan,
Do I place this JavaScript in the page header, or above the "selection combo
box to which it is being applied? If you had the code of an actual page I
can explore that would enable me to see how it must be put together to work
correctly. Thanks for the script and your help.

This is from the page at
http://gutterstar.net/cgi-bin/forum/index.php?showtopic=339
This JavaScript function will toggle the hiding or showing of any element or
section based on the ID passed to the function.
CODE
<script type="text/javascript">
function toggleHide(eID) {
var e = document.getElementById(eID);
if (e.style.display == 'block') {
e.style.display = 'none';
e.style.visibility = 'hidden';
} else {
e.style.display = 'block';
e.style.visibility = 'visible';
}
}
</script>
To use it, you simply put the following attribute in your element.
onchange="toggleHide('IDOfElementToToggle')"
So, when the element with the attribute above changes, it will hide or show
the element with the attribute of
id="IDOfElementToToggle"
Hope this helps,
Bryan
