Vector3 and CFrame conversion?

Hiaa guys. Sorry again sorry for all the questions ;). Quick quesion here, about Vector3 and CFrame values. I want to know how to convert a value from CFrame to Vector3 and vice - versa. Here's an example:

wait(2)
blue = game.Workspace.BlueSpawn
red = game.Workspace.RedSpawn
Var = 0
players = game.Players:GetChildren()

function SpwnTele()
    print(player.Value.Value)
        if player.Value.Value=="blue" then
        player.Character.Torso.CFrame = CFrame.new(Vector3.new(blue.Position)) --heres the line I need help with
        print(player.Character.Torso.CFrame)
        else
        player.Character.Torso.CFrame = CFrame.new(Vector3.new(red.Position)) --and this one too
        print(player.Character.Torso.CFrame)
        end
    end

for i,v in pairs(players) do
    if Vteam==nil then
        player = v
        Vteam = Instance.new("StringValue")
        Vteam.Parent = v
        Var = math.random(1,2)
        if Var==1 then
            Vteam.Value = "red"
            SpwnTele()
        elseif Var==2 then
            Vteam.Value = "blue"
            SpwnTele()
        end
    end
end

Sorry if the script is a bit long. If you find a errors within the script, speak up! (BTW the script is supposed to create a string value for each player then pick a random team color, from which the player will be teleported to the corresponding Part with that color.) THX!!
