why I have this error "attempt to index field'LocalPlayer' (a nil value)" ???

Good morning, everyone, So I'm making a tycoon and I want when I pass on the collector, to get the money back so I made this script:

script.Parent.Touched:Connect(function(hit)
	if hit.Parent:FindFirstChild("Humanoid") then	
		game.Players.LocalPlayer.leaderstats.Cash.Value = game.Players.LocalPlayer.leaderstats.Cash.Value + script.Parent.Parent.Screen.amount.Value
	end	
end)

And when I run the script I get the following error: "attempt to index field'LocalPlayer' (a nil value)", I looked on other forums but nothing, I don't know what to do. Help me please

This should work:

script.Parent.Touched:Connect(function(hit)
    if hit.Parent:FindFirstChild("Humanoid") then
	local Player = game.Players:GetPlayerFromCharacter(hit.Parent) --  get the player from the character
	local Cash = Player.leaderstats.Cash
        Cash.Value = Cash.Value + script.Parent.Parent.Screen.amount.Value
    end 
end)

If it helped, remember to accept! :D

Thank you Xviperlink, but now, I have this error: "Player is not a valid member of DataModel"
