That's right! I didn't even notice the single checkbox part of this. If you
look at the length of the checkbox array and get undefined, you only have
one checkbox, so there's no need to bother with separate scripts. I think
this would work for you:
function checkForNoSelections() {
var e = document.viewItems;
if (!e.atccNum.length && e.attcNum.checked) {
return true;
}
for (var i = 0; i < e.atccNum.length; i++) {
if (e.attcNum[i].checked) {
return true;
}
}
alert('You must select an item to display.');
return false;
}
