I think the thing confusing you is that the LV variant isn't exactly the same as the OLE variant. The LV variant can be any LV type, or any OLE type including an OLE variant. So, the variant probe in LV will often show you just a little bit about the type since it doesn't really know enough about how to display it. If you can use the To G Data node to convert the variant to your type and then probe or display in indicators, then everything is working fine. Without the extra typing information provided by the To G Data, LV just doesn't know enough to make a decent probe, at least not today. Greg McKaskle
