Model-To-Script generator gives no output. Why?

print([[
local model = Instance.new("Model",game.Workspace)
]])
local toconvert = game.Workspace["Observation Tower"]
local childrentable={}
local childrennumber=0
sentchildrentable=false
function mainloop(children)
for i=1,#children,1 do
    childrennumber=childrennumber+1
    wait()
    if i==#children then
    for i=1,#childrentable,1 do
        if sentchildrentable==false then
        wait(0.1)
    mainloop(childrentable[i]:GetChildren())
    sentchildrentable=true
    else
    if children[i]:IsA("Model")==false and children[i]:IsA("Folder")==false then
    print("local child"..childrennumber.."=Instance.new("..children[i].ClassName..",model)")
    else
    table.insert(childrentable,children[i])
end
end
end
end
end
end
local toconvertchildren = game.Workspace["Observation Tower"]:GetChildren()
mainloop(toconvertchildren,0)

It gives NO Output. doesn't error, doesn't print.
