Vista - Create website with multiple host headers

I am trying to add multiple host headers to a new website I am creating. I
am using VBScript and WMI to create the test site. The code below is taken
from Microsoft's example of using the IIS WMI provider

My question is if I wanted to add another host header how should it be done?

Currently I get a "Subscript out of range error" when I try to add to the
array.

' Make connections to WMI, to the IIS namespace on MyMachine, and to the WWW
service.
set locatorObj = CreateObject("Wbemscripting.SWbemLocator")
set providerObj = locatorObj.ConnectServer("MyServer", "root/MicrosoftIISv2")
set serviceObj = providerObj.Get("IIsWebService='W3SVC'")

' Build binding object, which is a required parameter of the CreateNewSite
method.
' Use the SpawnInstance WMI method since we are creating a new instance of
an object.
Bindings = Array(0)
Set Bindings(0) = providerObj.get("ServerBinding").SpawnInstance_()
Bindings(0).IP = ""
Bindings(0).Port = "80"
Bindings(0).Hostname = "host-header-1"
Bindings(1).IP = "" <== Added by me
Bindings(1).Port = "80" <== Added by me
Bindings(1).Hostname = "host-header-2" <== Added by me


' Create the new Web site using the CreateNewSite method of the
IIsWebService object.
Dim strSiteObjPath
strSiteObjPath = serviceObj.CreateNewSite"MyNewSite",Bindings,
"D:\Inetpub\VSERVER")
