If the group is local to a function then you can’t remove it from outside that function. But if you localize it outside the function then you can. Example:

[lua]local childGroup, parentGroup
local parentGroup = display.newGroup()

local function doSomething()
childGroup = display.newGroup() --This is still local because of the previous variable
parentGroup:insert(childGroup)
end

display.remove(childGroup) --This will remove the child group from the parent group.
childGroup = nil[/lua]

Hope that helps!

:frowning: how fix it?
function scene:createScene( event )
local screenGroup = self.view

Layer_Fondo = display.newGroup();
screenGroup:insert(Layer_Fondo);
function pintarFondo()
imgFondo = movieclip.newAnim({“imagenes/img_fondo_flags.png”},320,480)
imgFondo.x = display.contentWidth / 2
imgFondo.y = display.contentHeight / 2
imgFondo:stop()
Layer_Fondo:insert(imgFondo)
end

function removeFondo()
display.remove ( Layer_Fondo ) --???
Layer_Fondo = nil --???
end

pintarFondo()
removeFondo() — NOT WORK IT

If you are using storyboard you can declare Layer_Fondo before function scene:createScene, if you declare inside that function it only can be handled in that function. This will do the trick:

local Layer_Fondo;

function scene:createScene( event )
local screenGroup = self.view

Layer_Fondo = display.newGroup(); [import]uid: 131209 topic_id: 26039 reply_id: 105447[/import]
