What's the proper way to prevent multiple touch events going off when providing rewards?

I have this obstacle course demo. It spawns a map, the player completes it and touches a win block. This block is meant to increment the number of wins the player has. However, it goes off more than once when the player initiates contact with the block. I have attempted to create a table to store past winners to avoid this, but it will not work.

local beenAwarded = {} --used to store winner names (those who touched the block)

script.Parent.Touched:connect(function(hit)
		if hit.Parent:FindFirstChild("Humanoid") then
			local character = hit.Parent.Humanoid
			print "human found"
			local plrname = hit.Parent.Name
			local plr = game.Players:FindFirstChild(plrname)
			if plr then
				local stats = plr:FindFirstChild("leaderstats")
				if stats then
					wait(.1)
					plr.Character.HumanoidRootPart.CFrame = CFrame.new(game.Workspace.SpawnLocation.Position)
					if beenAwarded[plr] then return end -- if the player has been added to the table it ends the function
					table.insert(beenAwarded, plr) -- otherwise the player is added here (i have tried the same thing using the player name, same result)
					local wins = stats.Wins
					wins.Value = wins.Value + 1
			end
		end
	end
end)
