In addition to Nate's solution you could also use the this keyword onblur to
do what you want, and you dont have to think about the names.
<script>
var total = 0;
function addVal(number) {
//adds passed value to running total
var total += number;
//sets hidden field to current running value
document.formname.total.value = number;
}
</script>
<input type="text" name="#dynamic#" onblur="addVal(this.value);">
<input type="hidden" name="total" value="0">
I just typed this up, so there might be a type somewhere. You would probably
also want to do check if the passed value is numeric before adding it too.
function isNumeric(string, ignoreWhiteSpace) {
if (string.search) {
if ((ignoreWhiteSpace && string.search(/[^\d\s]/) != -1) ||
(!ignoreWhiteSpace && string.search(/\D/) != -1)) return false;
}
return true;
}

Subject: Jscript totalling with dynamic CF Fields..
