Re: snapshot reminder notification advice

I don't get any errors.  I'm posting my script that I'm using.  I've even dumbed it down to not go through the foreach look.  When I look at the members $SnapshotInfo = Get-SnapshotExtra $snap[0] it doesn't contain the creator property "aka NoteProperty". I don't confess to be a newbie at powershell although I'm not sure why the property isn't being set.  I've been trying to debug with PowerGUI (which crashes), Am I missing something obvious?
