"is not a valid member of Model"? [SOLVED]

So. I have a script and a model with BackBoard and HeadBlock. The headblock script works fine, and they're both in the same model, but when I try activating the BackBoard script,

11:15:37.697 - BackBoard is not a valid member of Model
11:15:37.697 - Script 'Players.Player.PlayerGui.GUI.Frame.BB.Script', Line 2
11:15:37.698 - Stack End

BackBoard

script.Parent.MouseButton1Click:connect(function()
    if game.Workspace.NDeployed.BackBoard.Transparency == 1 then
        game.Workspace.NDeployed.BackBoard.Transparency = 0
    else
        game.Workspace.NDeployed.BackBoard.Transparency = 1
    end
end)

HeadBlock

script.Parent.MouseButton1Click:connect(function()
    if game.Workspace.NDeployed.HeadBlock.Transparency == 1 then
        game.Workspace.NDeployed.HeadBlock.Transparency = 0
    else
        game.Workspace.NDeployed.HeadBlock.Transparency = 1
    end
end)
