Badge not awarding when gear touches brick?

Ive got a gear called Coolboy6153 and it should award a badge when i touch a brick with it.

local badgeID = 359826248
local badgeService = game:GetService("BadgeService")
function onTouched(part)
	local playername = part.Parent.Parent.Parent.Name
	local player = game.Players:FindFirstChild(playername)
	if part.Parent.Name == "Coolboy6153" then
		badgeService:AwardBadge(player.userId, badgeID)
	end
end
script.Parent.Touched:connect(onTouched)

Error: Workspace..Torso.Script:7: attempted to index local 'player' (a nil value)
