Whats the best way to fix my on win script? Its not awarding stuff to the leaderboard!

Does anyone know?

amnt = 1 --how much you get for it

return function(winner)
	function onTouched(part)
		local h = part.Parent:findFirstChild("Humanoid")
		if (h~=nil) then
			local thisplr = game.Players:findFirstChild(h.Parent.Name)
		if (thisplr~=nil) then
			local stats = thisplr:findFirstChild("leaderstats")
		if (stats~=nil) then
			local score = stats:findFirstChild("Wins")
		if (score~=nil) then
			score.Value = score.Value + amnt
				end
			end
		end
	end
end

end

I suggest putting a server script in the win part that contains this script:

local amnt = 1

script.Parent.Touched:Connect(function(hit)
	if hit.Parent:FindFirstChildWhichIsA("Humanoid") then
		local plrName = hit.Parent.Name
		local plr = game.Players:FindFirstChild(""..plrName)
		if plr ~= nil then
			if plr.leaderstats ~= nil then
				local stat = plr.leaderstats.Wins
				stat.Value = stat.Value + amnt
			end
		end
	end
end)

see if this works
