Exactly how to group players

I’m having trouble figuring out how to make my sonos players group. I have a scene that does the following:

Leave group (to disassociate any previous groupings)
Select device (IP of player 1)
Play URI (plays the specified pandora channel and sets the volume)

That works fine. However, I tried to add:
Select device (IP of player 2)
JoinGroup (Name of the zone to join)

This does NOT result in grouping player 1 and player 2.

I did see an old thread with a screenshot that showed the PlayURI option having a selection for grouping but my PlayURI does not have that option.

Any suggestions??
