HTA to feed VBS Variable

I have a vbs file that runs a .hta with two radio buttons. My objective is to capture the selection made in the .hta and bring it back to the vbs to use it as a variable for a drive mapping.

The vbs has
Code: 
Set WSHNetwork = CreateObject("WScript.Network")
WSHNetwork.MapNetworkDrive "Z:", "\\" & GSServer & "\goldapp$",True

The GSServer should equal whatever is selected in the .hta.
Here's the .hta:
Code: 
<SCRIPT LANGUAGE="VBScript">

Sub RunScript

    If ComputerOption(0).Checked Then
        strComputer = ComputerOption(0).Value
    End If
    If ComputerOption(1).Checked Then
        strComputer = ComputerOption(1).Value
    End If
    If strComputer = "" Then
        Exit Sub
    End If

End Sub

Sub CancelScript
   Self.Close()
End Sub

</SCRIPT>

<BODY>
<input type="radio" name="ComputerOption" value="GOLD">GOLD<BR>
<input type="radio" name="ComputerOption" value="GSPROD">GSPROD<P>

<input id=runbutton class="button" type="button" value="Run Script" name="ok_button" 
onClick="RunScript">
&nbsp;&nbsp;&nbsp;
<input id=runbutton class="button" type="button" value="Cancel" name="cancel_button" 
onClick="CancelScript">

</BODY>

So how do I get the radio button selected and bring it back into the vbs file that runs the .hta?

Why not having all the code in the HTA ?

Hope This Helps, PH.

There is a lot more going on here that I haven't described. I've got a manual process that involves uninstalling an application, deleting associated directories/files, then re-installing the application, mapping a drive, and making several other changes.

But most of the changes require no intervention from the user, they are being done in silent mode. The only time I need a user interface is for selecting a server name (from two possibilities) to map the drive.

Have the hta collecting all the necessary parameters and then do the job(s).

OK, I tried that and I'm getting an error message indicating Object required: 'wscript'

For this line:
Set WSHShell = wscript.createObject("wscript.shell")

And what about this ?
Set WSHShell = CreateObject("WScript.Shell")

Looks better...but I've got a couple Wscript.sleep commands in there as well. They are bombing out...is there another hta-friendly format for waiting or sleeping to let one process finish before starting the next?

let one process finish before starting the next
How are the process started ?
Have a look at the 3rd argument of the Run method.

Try to load an external vbscript to let it run the sleep.
I don't think Wscript.exe is reachable from HTA

Code: 
<SCRIPT LANGUAGE="VBSCRIPT" SRC="Sleep.vbs">
</SCRIPT>

There are ways, but you have to write your HTA more like a VB program using forms rather than a sequential script. In other words you need to use events and timers, and poll for completion.

Here's a simple example:

HTAVBS.vbs
Code: 
With WScript
  .Sleep 10000
  .Quit 47 'Return result to HTA.
End With

HTAVBS.hta
Code: 
<HTML>
<HEAD>
  <TITLE>
    HTAVBS: Start a WSH Script, Wait For Completion
  </TITLE>
  <HTA:application scroll=no>
  <STYLE>
    div.clsIndent {margin-left: 30px}
    div.clsIndentRed {margin-left: 30px; color: red}
  </STYLE>
  <SCRIPT language=VBScript>
    Option Explicit
    Const WshRunning = 0
    Const WshFinished = 1
    Dim wshShell
    Dim wseExternal
    Dim tmrExternal

    Sub cmdStart_onclick()
      On Error Resume Next
	  Set wseExternal = _
	    wshShell.Exec("wscript.exe //NOLOGO HTAVBS.vbs")
	  If Err.number <> 0 Then
	    lblStatus.innerText = "Failed to start!"
	  Else
	    lblStatus.innerText = "Started"
	    cmdStart.disabled = True
	    cmdReset.disabled = True
        tmrExternal = _
          window.setInterval("tmrExternal_timer", _
                             1000, _
                             "VBScript")
      End If
    End Sub
    
    Sub cmdReset_onclick()
      lblStatus.innerText = "Ready"
      lblResults.innerHTML = ""
      lblMore.innerHTML = ""
      cmdReset.disabled = True
      cmdStart.disabled = False
    End Sub
    
    Sub Continue()
	  lblMore.innerHTML = _
	      "More, more, more.<BR>" _
	    & "Do some more work in the HTA.<BR>" _
	    & "Work done."
	  cmdReset.disabled = False
    End Sub

    Sub tmrExternal_timer()
      With lblStatus
        If wseExternal.Status = WshRunning Then
          If .className = "clsIndentRed" Then
            .className = "clsIndent"
          Else
            .className = "clsIndentRed"
          End If
        Else
          window.clearInterval tmrExternal
          .innerText = _
              "Finished. Exit code " _
            & CStr(wseExternal.ExitCode)
          .className = "clsIndent"
          Set wseExternal = Nothing
          window.setTimeout "Continue", 200, "VBScript"
        End If
      End With
    End Sub

    Sub window_onload()
      Set wshShell = CreateObject("WScript.Shell")
    End Sub

    Sub window_onunload()
      Set wshShell = Nothing
    End Sub
</SCRIPT>
</HEAD>
<BODY>
  <DIV>
    <INPUT type=button id=cmdStart value="Start WSH Script"> 
    <INPUT type=button id=cmdReset value=Reset disabled>
  </DIV>
  <H3>External task status:</H3>
  <DIV id=lblStatus class=clsIndent>Ready</DIV>
  <H3>More work here in the HTA:</H3>
  <DIV id=lblMore class=clsIndent></DIV>
</BODY>
</HTML>
The [tt]Continue()[/tt] subroutine is just there to perform any synchronous logic you want to run following WSH script completion and clearing of the wait timer.

Alas, I left some junk in there when I trimmed this down to a sample.

Delete line 38:

[tt]lblResults.innerHTML = ""[/tt]

Sorry.

Thanks for all the responses and the code example guys. I have gone the route of adding additional buttons to the HTA in order to run various processes...
