Indexing objects in a table

Getting Started Newbie Questions

I have a table inside a table and I’m trying to index both of its places in each table,… so eventually I can remove it.  The child table that I call group returns the proper index number, but the parent table returns nil.  Please help.

[lua]drawTable = {}

group = {}

function label(obj)

print(  table.indexOf(drawTable, obj)  )

print(  table.indexOf(drawTable[1], obj)  )

end

drawTable[#drawTable+1] = group

drawTable[#drawTable][#group+1] = display.newRect(50,50,50,50)

drawTable[#drawTable][#group+1] = display.newRect(50,50,50,50)

label(  drawTable[#drawTable][2]  )[/lua]
