Why does it say that team is a nil value?

local owner = script.Parent.Parent.Owner

local function OnClick (Player)
    local HaveTeam = Player:FindFirstChild("HaveTeam")
    if Player ~= nil then
        if HaveTeam.Value ~= true then
            Player.HaveTeam.Value = true
            owner.Value = Player.Name
            local team = Instance.new("Team")
            team.Name = owner.Value.."'s Tycoon"
            team.TeamColor = BrickColor.new("Bright red")
            team.Parent = game:GetService("Teams")
            Player.Team.TeamColor = BrickColor.new("Bright red")
            script.Parent.Parent.Mine.Button.Script.Disabled = false
            script.Parent:Destroy()
        end
    end
end

script.Parent.ClickDetector.MouseClick:Connect(OnClick)

Error is in line 13 Workspace.Sample.TeamChanger.Script:13: attempt to index field 'Team' (a nil value)
