Adding 500 to a leaderboard for a certain person?

so my leaderboard code is below or wherever but I wanna be a able to press a button and add money to only me. I have a button in a frame in starter Gui I have code to make it so only I can have it and I wanna make it so If I press the button it adds 500 only me and not others. I also have a frame in starter gui that shows your money so if that's a problem let me know

game.Players.PlayerAdded:connect(function(player)
	local leader = Instance.new("Folder",player)
	leader.Name = "leaderstats"
	local Cash = Instance.new("IntValue",leader)
	Cash.Name = "Cash"
	Cash.Value = 0
end)

The gui that shows your amount of money

local Cash = script.Parent.Parent.Parent.Parent.Leaderstats.Cash
Cash.Changed:connect(function()
	script.Parent.Text = "Cash: $"..Cash.Value
end)

In ServerScript:

game.Players.PlayerAdded:connect(function(p)
	if p.Name="YourName"
		g = Instance.new("ScreenGui",p.StarterGui)
		u = Instance.new("TextButton",g)
		i = p.leaderstats.Cash.Value
		u.MouseButton1Down:connect(function()
			i=i+500
		end)
	end
end)

Just change the name of "Cash" to "Cash"
