let me see if I understand:
you enter a name in a textfield. This name then gets added into an array. Another button then chooses a random item from that array.

now, when a name is added, should it be added permanently to the page? so that you could come on on another PC and see the name there. Or should the whole list clear when the user leaves the page?

If you dont want it permanent, then just do this:

<html>
<head>
<title>Untitled Document</title>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
<script language="JavaScript">
list = new Array()
function add() {
document.getElementById('list').innerHTML = ""
list[list.length] = document.getElementById('name').value
for (i=0; i<list.length; i++)
{
document.getElementById('list').innerHTML += list[i] + "<br>"
}
}
function choose() {
alert(list[Math.round(Math.random()*(list.length-1))])
}
</script>
</head>

<body>
<input type="text" value="enter name here" name="name">
<input type="button" value="add" onClick="add()"><br>
<input type="button" value="choose random" onClick="choose()">
<br>
<span id="list"></span>
</body>
</html>

If you want it permanent, then I would suggest PHP.
