Hello,
I have a javascript code (a part of it is in php) that populates a pull-down menu. It works perfectly well with Explorer, Netscape and Firefox under Windows. But impossible to make it work with Explorer or Safari under Mac!!!
Is javascript different between windows and mac?
Here's the code, if anyone has the slightest idea or suggestion.

Thanks a lot in advance!

Gaston.

<SCRIPT type="text/javascript">

function MultiDimensionalArray(iRows,iCols)
{
var i;
var j;
var a = new Array(iRows);
for (i=0; i < iRows; i++)
{
a[i] = new Array(iCols);
for (j=0; j < iCols; j++)
{
a[i][j] = "";
}
}
return(a);
}

function updateDirMenu(form,groupMenu,selectedIndex,selectedGroup, startDirValue){
var numdiringroup = Array()
var dirArray=MultiDimensionalArray(35,0)
var new_index=-1;
var groupPrefs = "<?=$group_prefs?>";
var change = 0;

if (selectedGroup == undefined) {
change = 1
if (groupPrefs != "") {
selectedGroup = groupPrefs}
}


<?php
$x = 0;
$numdiringroup = 0;
