You could try using StaticVarSet in your main pane. Then, refer to 
  the
values using StaticVarGet in the sub panes. You might have to use 
  the
View | Refresh All menu item to get the other panes to update 
  after
making any changes in the main pane, else activate each one in turn 
  to
have them update automatically upon activation.
