Why does my Teleporter Teleport above a part?

So i made two parts, When you touch one off them it Telports you to the other part. Same with the other part. The two parts are inside a building and for some reason they tp up on the roof instead off the 1st floor to 2nd floor. Heres a screenshot (link to screenshot) to understand better:

Hey! to get rid of that problem use CFrame instead of vector3!

PartOne.Touched:Connect(function(Hit)
	if Hit:IsA("Humanoid") then
		local Player = game.Players:GetPlayerFromCharacter(Hit.Parent)
		Player.Character:SetPrimaryPartCFrame(X,Y,Z)
	end
end)

It's quite simple, the player touches a part, and it teleports them to a specific Coordinate Frame, this is related to Vector3 but CFrame can supply much more than XYZ, containing the possibility to use Radians and etc.
