Grabbing Post Var From <select Mulitple

[sonesay 7]

First off im not sure if it goes in PHP or xhtml section this code deals with both. I have 2 pages there is a button on the first that opens a new window and displays 2 select forms. Once selections have been made when you submit it gets submited to first main window and the second window is closed. Im having trouble trying to grab the selected options.

note: the output of the options are from my database so maybe you can fill them with dummy options when you do testing.


groups_index.php

echo $_POST['group2'];
}


?> linenums:0'><script LANGUAGE="JavaScript">window.name="main_index";function openFormWindow(){ OpenWindow=window.open("groups.php", "newwin", "height=250, width=400,toolbar=no,scrollbars=no,menubar=no,location=no, resizable=no");}</SCRIPT><input type="button" onclick="openFormWindow();" value="Open Form" /><?phpif (isset($_POST['group2'])) { echo $_POST['group2'];}?>
groups.php

function addUser(toGroup,fromGroup) {
var listLength = document.getElementById(toGroup).length;
var selItem = document.getElementById(fromGroup).selectedIndex;
var selText = document.getElementById(fromGroup).options[selItem].text;
var selValue = document.getElementById(fromGroup).options[selItem].value;
var i; var newItem = true;
for (i = 0; i < listLength; i++) {
if (document.getElementById(toGroup).options.text == selText) {
newItem = false; break;
}
}
if (newItem) {
document.getElementById(toGroup).options[listLength] = new Option(selText, selValue);
document.getElementById(fromGroup).options[selItem] = null;
}
}

function saveGroup() {
var strValues = "";
var boxLength = document.getElementById('grouplist2').length;
var elcount = 0;
if (boxLength != 0) {
for (i = 0; i < boxLength; i++) {
if (elcount == 0) {
strValues = document.getElementById('grouplist2').options.value;
} else {
strValues = strValues + "." + document.getElementById('grouplist2').options.value;
}
elcount++;
}
}
if (strValues.length == 0) {
document.forms['groupsform'].submit();
} else {
document.forms['groupsform'].group_users.value = strValues;
document.forms['groupsform'].submit();
}
}
</script>

update: sorry guys i didnt change the saveGroup() it was refering to the old name grouplist2. I changed it now and its work so far. Well hopefully someone will find this useful.
