the saveList() function works. I tried to write the loadList() function to repopulate the select options, but I'm obviously doing something wrong at the end of the code. In my test I save 3 items and when it repopulates it does create 3 options, however only the first option contains the proper text and value and the other 2 display undefined. Here's the code:

function saveList() {
var newList = document.amp.playlist.options;
var j, len = newList.length;
var Sngstr = "";
for (j = 0; j < len; j++) {
if (Sngstr.length > 0) Sngstr += &quot;&&quot;;
Sngstr += newList[j].value + &quot;|&quot; + newList[j].text;
}
setCookie (&quot;TheList&quot;,Sngstr,expdate);
}

function loadList() {
var i, j;
playList = document.amp.playlist.options;
TheList = getCookie(&quot;TheList&quot;);
if (TheList != null) {
listArray = TheList.split(&quot;&&quot;);
for (i = 0; i < listArray.length; i++) {
j = i + 1;
piecesArray = listArray.split(&quot;|&quot;);
//Below is where something seems to be wrong
var no = new Option();
no.value = piecesArray;
no.text = piecesArray[j];
playList[playList.length] = no;
}
}
}

Any ideas?
 
The problem is solved, but in case you want to know how it's done (thanks to Dave Clark of Dave Clark's consulting) it looks like this:

function loadList() {
var playList = document.amp.playlist.options;
var TheList = getCookie(&quot;TheList&quot;);
if (TheList != null) {
var listArray = TheList.split(&quot;&&quot;);
var j, v, len = listArray.length;
for (j=0; j<len; j++) {
v = listArray[j].split(&quot;|&quot;);
playList[playList.length] = new Option(v[1], v[0]);
}
}
}
