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)
