What is wrong with this script?

Here is my script. It is a simple code that on click, the object will be removed and the player's leaderstats ("Money") will be increased. I can't find anything wrong with it, but some of you might. The error is "Workspace.Handle.ClickDetector.Script:6: attempt to index a nil value" The teapot disappears, BUT the leaderstats remain the same.

local teapot = script.Parent.Parent

script.Parent.MouseClick:connect(function(playerWhoClicked)
teapot.Transparency = 1
teapot.CanCollide = false
playerWhoClicked:FindFirstChild("Money").Value = playerWhoClicked:FindFirstChild("Money").Value + 125
end)

The problem is that the 'Money' leaderstat is inside of leaderstats, not the player..

player>leaderstats>Money

Do this;

local teapot = script.Parent.Parent

script.Parent.MouseClick:connect(function(plr)
	teapot.Transparency = 1
	teapot.CanCollide = false
	local money = plr.leaderstats:FindFirstChild('Money')
	if money then --Check if it's there.
		money.Value = money.Value + 125
	end
end
