Listbox Retrieval Problem

Hello everyone, I am writing an hta to install printers for people. You pick a department from one listbox, then another listbox shows you which printers are in that department. When you select a printer, a description of the printer is displayed. Choose if you want to set it as your default or not and hit install printer. This is working just fine, but there is a problem with my selecting the printer name from the second listbox. Instead of installing the printer that was selected, it installs the first one in that department. I believe this is my problem right here:
Code: 
SelectedPrinter = form.List2.options[form.List2.selectedIndex].text;
Here is the rest of the hta, so you get a better idea of everything.

Code: 
<html>
<head>
<title>Install Network Printer</title>
<HTA:APPLICATION
  ID="objInstallPrinter"
  APPLICATIONNAME="Greetings"
  SCROLL="yes"
  SINGLEINSTANCE="yes"
  WINDOWSTATE="normal">
</head>

<script language="javascript">
<!--
function setOption(form, index) {
  for (var i = 0; i < form.List2.length; i++) {
    form.List2.options[i].text = "";
    form.List2.options[i].value = "";
  }
  
    if (index == 0) {
    	form.List2.options[0].text = "";
    form.List2.options[0].value = "";
    }
  else if (index == 1) {
    form.List2.options[0].text = "pamholpr001";
    form.List2.options[0].value = "Accounting LaserJet 8000";

Well of course, you're setting the selectedIndex to zero two lines above that one:
Code: 
  [red]form.List2.selectedIndex = 0;[/red]
  form.ValueIn2.value = form.List2.options[form.List2.selectedIndex].value;
  SelectedPrinter = form.List2.options[form.List2.selectedIndex].text;
Either remove that line or move it.

pickletech,

[1] SelectedPrinter is not in-sync after onchange fired from List2.
[2] Just in case for win9x/me, AddWindowsPrinterConnection will need a second parameter.

A brut-force revision is something like this.
[tt]
<select name="List2" OnChange="this.form.ValueIn2.value=this.options[this.selectedIndex].value[blue];SelectedPrinter=this.options[this.selectedIndex].text;[/blue]">
[/tt]
and that if for win9x/me, you need this. (But for winnt series, your line is okay.)
[tt]
objNetwork.AddWindowsPrinterConnection "\\PrintServer\" & SelectedPrinter [blue]document.ThisForm.ValueIn2.value 'win9x/me only[/blue]
[/tt]
You can make some re-design (global variable setting, variable passing between handlers) to make thing tidier.

No, tried that and it had no effect, because that only runs when you select from the first listbox. Which I had totally looked over until you said that. I'm an idiot. I created a new function that runs when you select from the second listbox and its all gravy now. Thanks for your help. Since your post led me very quickly to solve this I will still give you some credit. Thank You,

Haha, thanks tsuji. Apparently you solved it while I was writing my last reply. For pointing out my bonehead mistake you can get a star too. :)
