Call out to script to stop with attribute in wWWHomePage

Answer 1

You have:

If wWWHomePage 6 Then

I'm assuming you want it to say:

 If wWWHomePage = 6 Then

Since the missing "=" will cause an error, but since that code really doesn't do anything anyway, other than just abort the script, you could simplify your code by only taking action if that value is not set, for example:

If objItem.Get("wWWHomePage") <> 6 Then
  Set ppt = CreateObject("PowerPoint.Application")
  ppt.Visible = True
  ppt.Presentations.Open "\\abngan01\tracking\ppt.pptx"
End If

I'm also assuming "6" is some sort of flag you've set yourself, you might want to use something a little more descriptive like "PPTSTATUS006", or something along those lines.
