How to teleport someone in roblox?

I have three problems: 1. I can't teleport players correctly, sometimes they still spawn in the original spawn point and would take several clicks before he teleports into the right one.

1. Debounce won't work, you can still keep on teleporting.

2. Error at line "player.Character.Torso.CFrame" expected CFrame, given Vector3.new("") value.

ClassHolder = script.Parent
ct = ClassHolder.CounterTerrorists
t = ClassHolder.Terrorists
ctspawn = game.Workspace.ctspawn --spawnpoint
tspawn = game.Workspace.tspawn --spawnpoint
Spectators = game.Workspace.Spectators
player = game.Players.LocalPlayer

Teamjoined = false

ct.MouseButton1Down:connect(function()
    if Teamjoined == false then
        player.TeamColor = BrickColor.new('Really blue')
        player.Character.Torso.CFrame = Vector3.new(ctspawn.Position.X,ctspawn.Position.Y + ctspawn.Size.Y / 2 + 7,ctspawn.Position.Z)--This line Error CFrame expected
        player:LoadCharacter()
        ClassHolder.Visible = false
        Teamjoined = true
    elseif Teamjoined == true then
        print('You already joined a team')
    end
end)    

t.MouseButton1Down:connect(function(t)
    if Teamjoined == false then
        player.TeamColor = BrickColor.new('Really red')
        player.Character.Torso.CFrame = Vector3.new(tspawn.Position.X,tspawn.Position.Y + tspawn.Size.Y / 2 + 7,tspawn.Position.Z)--This line Error CFrame expected
        player:LoadCharacter()
        ClassHolder.Visible = false
        Teamjoined = true
    elseif Teamjoined == true then
        print('You already joined a team')
    end
end)
