IntValue script working for a solo player but when two players are present it breaks ?

In a solo server it works perfectly as intended, but with 2 players when one of them walks through the door it works until the other player walks through, which gives this error:

(the puzzle is to walk through a door 5 times locally to wake up the owner of the store)

local detection = game.Workspace.detectionzone
local employee = game.Workspace.ToFind["Snailmart Employee"]
local playere = game.Players.LocalPlayer
local db = false
local ReplicatedStorage = game:GetService("ReplicatedStorage")
local employee2 = game.Workspace.minimumwagesnail
local employee3 = game.Workspace.wakeupsnail

	local please = Instance.new("IntValue",playere)
	please.Name = "Beeps"
	print(please.Value)
	wait(.5)

detection.Touched:Connect(function(hitpart)
	local PlayerFromCharacter = game:GetService("Players"):GetPlayerFromCharacter(hitpart.Parent)
	if PlayerFromCharacter then
		if db == false then
			db = true
			PlayerFromCharacter.Beeps.Value += 1
			detection.Sound:Play()
			wait(1.78)
			print(PlayerFromCharacter.Beeps.Value)
			if PlayerFromCharacter.Beeps.Value >= 5 then
				employee2.ding:Play()
				employee2.Sleep.Zs.Enabled = false
				employee2.Sleep.wakeup:Emit(1)
				employee.Position = Vector3.new(555.547, 30.827, -344.168)
				employee2.Sleep.wakeup.Enabled = false
					for _, part in pairs(employee2:GetChildren()) do
						if part:IsA("Part") or part:IsA("UnionOperation") then
						part.Transparency = 1
							for _, part2 in pairs(employee3:GetChildren()) do
								if part2:IsA("Part") or part2:IsA("UnionOperation") then
								part2.Transparency = 0
							end
						end
					end
				end
			end
			db = false
		end
		end
	end)	

(forgive my horrible looking code pls)
