How do i teleport the player (just one) to a certain place?

I tried:

game.Workspace.Player.Torso.Position = Vector3.new(-165.91, 1331.55, 302.289)

but it doesn't teleport the player there.

Second Question,

I have a Gui that gives the player the ability to choose their team (This would compare with my first question) that he/she choose. So say the player choose Team Red from a Gui, and it would teleport the player to the Red Team Spawn Location so I did this for something:

if game.StarterGui.GunPicker.NameOfGuns.For_PrimaryFrame.Gun_Name_Of_Pick.Text == '---' then
	DeployButton.Visible = false
	end

Don't worry about the stuff inside the if then statement.

So in the Outlook it said that NameOfGuns is not a valid member of ScreenGui One, the name of the Gui in it (NameOfGuns Parent) is not ScreenGui

So if anyone can help me with this problem I would be happy, thanks!
