Sprites/textures :Instantiate in a loop and load into an array

Hi,
I would like to create sprites inside a loop. Is this possible?
I've tried with jumping balls but got nowhere fast. I got attempt to index global
now I've tried with Hierarchy example and get the error main.lua:30: bad argument #1 to 'addChild' (Sprite expected, got nil)
Is what I want possible with sprites or textures? If not then how do you setup scenes with multiple instances of the same object quickly?

a={}
dot1tex = Texture.new("dot-1.png")
group1 = Sprite.new()
group1:addChild(Bitmap.new(group1tex))
for i=0,3 do
for j=0,3 do
local dot = Bitmap.new(dot1tex)
dot:setPosition(i * 45 + 10, j * 45 + 60)
a[i]=group1:addChild(dot)
end
end
group1:setPosition(10, 10)
for i=0,3 do
stage:addChild(a[i]) -- line 30
end |

Remember Lua table indexing starts at 1 and not at 0
