Need a tweak to this code

I'm fumbling a bit with this code.

Go OPENINRIGHT=vert Z:\Dropbox

That's exactly what I want, minus the folder tree. How do I also add in the tree? using NEW=tree opens a new Window, and I want it to be in the same window. Essentially just open the DropBox folder in Dual Vertical (with tree) mode, on the right side, keeping the current folder open in the left side.

You could just turn on Preferences / Folder Tree / Options / Open second Folder Tree in dual display mode, unless you don't always want a tree for the second display, in which case use this:

Set TREE=Right,On Go OPENINRIGHT=vert Z:\Dropbox

Second one is perfect, thanks!
