I was searching ALL over for a javascript to just add up a column of numbers and I found this one here in an old question.
It seemed to work great for my purposes EXCEPT it stops adding at four and I have more input fields than that.
I tried adjusting the
for (var i=1;i<=4;i++) { to
for (var i=1;i<=12;i++) {
to reflect the number of fields and thinking that was the issue but I got an error message about form elements being invalid.
If anyone has an idea of what I might try i would appreciate it.
<html>
<head>
<title></title>
<SCRIPT LANGUAGE="JavaS cript">
<!--
function sumIt() {
var f = document.forms["myForm"]
var s = 0
for (var i=1;i<=4;i++) {
var v = f.elements["Val"+i].value
v = parseFloat(v)
if (isNaN(v)) continue
v = Math.abs(v)
s+=v
}
f.elements["exptotal"].value = s
}
//-->
</SCRIPT>
</head>
<body>
<form name="myForm">
<p>
one: <input type=text name="Val1" onchange="sumIt ()">
</p>

two: <input type=text name="Val2" onchange="sumIt ()">
