ARS Rookie needing some help on a script?

Hi-

Let me first explain what I'm trying to do and then tell me if I'm even close or how to fix please!

I want to just automatically populate the address based on the office location after a new user is created in ARS.  So, I've already added the office location as part of the create user form and I started with the following VB script but it's not working.  Any help would be greatly appreicated from this point on.  I have many other locations but was just testing with this particular case before I do all of the other locations.

Sub onPostCreate(Request)

If Request.Class <> "user" Then Exit Sub

  DirObj.Getinfo
  Loc=DirObj.Get("physicalDeliveryOfficeName")

  If Loc = "Elk Grove" Then
    DirObj.put "streetAddress", "1050 W Arthur Ave"
    DirObj.put "l", "Elk Grove"
    DirObj.put "st", "Illinois"
    DirObj.put "postalCode", "60007"
    DirObj.put "c", "United States"
    DirObj.setinfo
  End If

End Sub

Again, thank you!
