Deleting Old Profiles

I have peiced together some script from various resources to try to accomplish this goal:

I want a script that will delete all local user profiles over 6 months old, except ones with the names:
            "Administrator"
            "All Users"
            "nvconfig"
            "OtherExamples"

Here is the Code I currently have, please help me figure out what I am doing wrong.

'=================================================================

Const LocalDocumentsFolder = "C:\Documents and Settings\"

set objFSO = createobject("Scripting.FileSystemObject")
set objFolder = objFSO.GetFolder(localdocumentsfolder)
set profolder = objFolder.SubFolders

on error resume next

for each fldr in profolder
      if not isexception(fldr.name) AND DateDiff("D", profolder.DateLastModified, Now) < 180 Then
                  'objFSO.DeleteFolder fldr.path, True
                  wscript.echo "Deleted Folder: " & profolder
      end if
next

Function isException(byval foldername)
      select case foldername
            case "All Users"
                  isException = True
            case "Default User"
                  isException = True
            case "nvconfig"
                  isException = True
            case "admin"
                  isException = True
            case "Administrator"
                  isException = True
            case Else
                  isException = False
      End Select
End Function
