<script language="JavaScript">
function popparent()

var elLearnObj = parent.document.forms[0].elements[4];
if(elCategory.options.length > 0){
var elCategoryCount = elCategory.options.length + 1;
}else{
var elCategoryCount = 0;
}
alert(elCategoryCount);
<?php
switch ($s) {
case 0:
$i=0;
while($row = $rs->fetchRow())
{
echo("elCategory[elCategoryCount]=new Option('$row[0]','$row[1]');n");
echo ("elCategoryCount++;n");

}
break;
case 1:
$i=0;
while($row = $rs1->fetchRow())
{
echo("elCourse[$i]=new Option('$row[0]','$row[1]');n");
$i++;

case 2:

RE: JavaScript array append and PHP
what do you have $rs $rs1 $rs2 and $rs3 defined as? Im still a little unclear about what your trying to do? Is this data being pulled from a database? I assume those variables are queries.
