How can I pass a whole group to another .lua?

I have tried with global variable like

function new()  
  
local gameGroup = display.newGroup()  
  
inventarioGroup = display.newGroup()  
  
return gameGroup  
end

in the next .lua, my next scene i just try to call inventarioGroup to front

function new ()  
  
 local gameGroup = display.newGroup()  
  
 local bg = display.newRect( 0, 0, 480, 320 )  
 gameGroup:insert( bg )  
  
 inventarioGroup():toFront()  
 -- I have tried "inventarioGroup:toFront() too  
  
 return gameGroup  
end

all I get is : attempt to call global ‘inventarioGroup’ (a nil value)

and i dont know why =S
please someone help me T_T
