This is my code:
<html>
<head>
<title>scoreboard</title>
<script>
function calculate() {
var sum=0; var total=0;
for (var i=0; i < document.questions.group1.length; i++){
if (document.questions.group1[i].checked){
sum = parseInt(document.questions.group1[i].value)
total = parseInt(total + sum);}}
for (var i=0; i < document.questions.group2.length; i++){
if (document.questions.group2[i].checked){
sum = parseInt(document.questions.group2[i].value)
total = parseInt(total + sum);}}
for (var i=0; i < document.questions.group3.length; i++){
if (document.questions.group3[i].checked){
sum = parseInt(document.questions.group3[i].value)
total = parseInt(total + sum);}}
alert(total)
}
</script>
</head>

<form name="questions">

answer b4: <input type="radio" name="group2" value="3"><br>
C:<br>
answer c1: <input type="radio" name="group3" value="0">
answer c2: <input type="radio" name="group3" value="1">
answer c3: <input type="radio" name="group3" value="2">
answer c4: <input type="radio" name="group3" value="3"><br><br>
<input type="button" value="total" onclick="calculate()">
</form>
</body>
</html>
How can I replace 'group[x]' in my code by a variable, so the three for-loops are replaced by one (because in reality there are a lot more questions and answers) ?
