Output is giving me viva is not a valid... of workspace?

function onClick(click)
	local viva = click.Name
	game.Workspace.viva.HumanoidRootPart.CFrame = CFrame.new(Vector3.new(-1632, 1.5, -1888))
end
script.Parent.ClickDetector.MouseClick:connect(onClick)

My output is giving me viva is not a valid member of workspace. Please Help

Because the MouseClick returns the Player who clicked, we can just access the player's Character, then the HumanoidRootPart.

function onClick(player) -- I shortened the playerWhoClicked to player.
    player.Character:WaitForChild("HumanoidRootPart").CFrame = CFrame.new(Vector3.new(-1632, 1.5, -1888))
end
script.Parent.ClickDetector.MouseClick:connect(onClick)
