How to enable a specific players gui?

So i have this script that goes inside my bullet, its simple, the bullets name is the player that shot it name. and the way it gets the correct player to enable the gui is that it tostrings bullet name and just do game.Players.(name).PlayerGui.ScreenGui.Visible = true. but when it attempts that it says attempt to index nil with screengui. how can i fix this? also the script is a normal script, not a local

function ont (hit)
	if hit.Parent.Name ~= (script.Parent.Name) then
		local humanoid = hit.Parent:findFirstChild("Humanoid")
		if humanoid ~= nil then
			local name = tostring(script.Parent.Name)
			script.Parent = workspace
			print("got hit")
			wait(0.2)
			
			--if humanoid.Health >= 1 then
			print("humanoid died")
				game.Players.name.PlayerGui.ScreenGui.Enabled=true
				wait(1)
			game.Players.name.PlayerGui.ScreenGui.Enabled=false
			--end
			
		end
	end
end
script.Parent.Touched:connect(ont)

You should use Players[name] instead of Players.name, because the second one is seen as Players["name"] which is not what you're looking for. So for example:

game.Players[name].PlayerGui.ScreenGui.Enabled = true
