I can't find a way for people to get Player Points when they click a block?

No one has bought any of my stuff yet but, I heard about the new infinite PP system. I have also used ClickDetector on my block and I have attempted to connect to a script which will give them player points.

script.Parent.MouseClick:connect(function(playerWhoClicked)
	local Reward = 1
	if playerWhoClicked.Character:findFirstChild("Humanoid") then
	game:GetService("PointsService"):AwardPoints(playerWhoClicked.userId, Reward)
	end
end)

-- I have not tested this. Put this in a Click Detector.
