Dave,
Here is a page of HTML that uses JavaScript to loop through all of the
elements of a form and set the checked value to true or false. I am not
sure how to specify that it only look at checkboxes, but since checked is
only a property of checkboxes (I think), the browser would just ignore an
attempt to change the checked property of other types of controls. You
could also explicitly state which boxes to uncheck:
document.myForm.cb2.checked = false;
Hope this helps.

<script language="JavaScript">
function inspectBox() {
if (document.forms[0].checkThis.checked) {
alert("The box is checked.");
} else {
alert("The box is not checked at the moment.");
}
}
function checkAll() {
for (var i in document.myForm) {
document.myForm.elements[i].checked = true;
}
}
function uncheckAll() {
for (var i in document.myForm) {
document.myForm.elements[i].checked = false;
}
}
