Dynamic groups have nothing to do with Subplots. Dynamic groups are only for sharing a piece of WHERE clause on a DB pen.

thanks, but then how do I get a new group name for the 5 - PPM?

Just put that group name in the .pens or .tagPens dataset for those pens. You don't have to create dynamic groups at all if you aren't using the where clause feature.

thanks
the most obvious things are the hardest to find.
