Can I add a third map on this Map-Changer Script?

I just came up with this script on the free models, yet it only says it can only have 2 maps

This is how it looks like:

-- Read Instructions for help
print("Change Map Script Loaded")
    while true do
    wait(1)
    game.Lighting.field1:clone().Parent = game.Workspace -- Put the maps in the lighting, and name then field1 and field 2
    wait(500) -- You can edit this, this is how long you wan't the field to be on. This is currently on 5 Minutes.
    local msg = Instance.new("Message")
    msg.Parent = game.Workspace
    msg.Text = ("message here")
    wait(4) -- How long you want the text to stay on your screen (editable)
    msg:remove()
    game.Workspace.field1:remove()
    wait(2) -- How long you want to wait for it to go away (editable) (I wouldnt edit it though)

       game.Lighting.field2:clone().Parent = game.Workspace -- this is the second map loading up, copy it un tix its at wait (1) and you will be able to make another map, so far there are 2 maps that can be loaded up field1 and firled 1
    wait(500) -- How long you want field2 to be up.
    msg.Parent = game.Workspace
    msg.Text = ("message here")
    wait(4) -- How long you want the text to stay on your screen (editable)
    msg:remove()
    game.Workspace.field2:remove()
    wait(1) --How long you want to wait for it to go away (editable) (I wouldnt edit it though)


end 

If I wanted to add a THIRD map, would this work?

(THE FIRST PART OF THE SCRIPT)

print("Change Map Script Loaded")
    while true do
    wait(1)
    game.Lighting.field1:clone().Parent = game.Workspace -- Put the maps in the lighting, and name then field1, field2 and field3

I replaced Field1 and Field2 into Field1, Field2 and Field3

And this is the code for the third map (Under the Second Map script)

game.Lighting.field3:clone().Parent = game.Workspace -- this is the second map loading up, copy it un tix its at wait (1) and you will be able to make another map, so far there are 3 maps that can be loaded up field1 and firled 1
    wait(500) -- How long you want field3 to be up.
    msg.Parent = game.Workspace
    msg.Text = ("message here")
    wait(4) -- How long you want the text to stay on your screen (editable)
    msg:remove()
    game.Workspace.field2:remove()
    wait(1) --How long you want to wait for it to go away (editable) (I wouldnt edit it though)

At the beginning, I replaced field2 into field3

Depending if in the lighting section, the maps names are correct for the script, could it work?
