[Solved ]Why does this script not detect this part even thought the part is in the workspace?

In my game, I'm working on making it work with filtering enabled. The issue is however, that this script can't detect haul which is defined on line 9, even though it's in the workspace. I don't know what is causing the connection error and can't seem to figure another way of doing this. If anyone could tell me why Haul won't connect, I would be very thankful. Here is the server script:

local ReplicatedStorage = game:GetService("ReplicatedStorage")
local colorChangeEvent = ReplicatedStorage:WaitForChild("Release")
local active = false

local function press(player, x)
    wait()
    local plr = player
    local char = player.Character
    local haul = char:findFirstChild("Haul")
    char.Latched.Value = false
    if haul.Value.Parent.Primary.Value == char then
        if haul.Value.Parent.Players.Number.Value > 1 then
            local torch = 1
            local max = haul.Part0.Parent.Players.Max.Value
            repeat
            local num = haul.Part0.Parent.Players:findFirstChild(torch)
            if num == nil then
                torch = torch + 1
                end
            if num ~= nil then
            haul.Value.Parent.Primary.Value = num
            num.Value.Humanoid.WalkSpeed = char.Humanoid.WalkSpeed
            num.Value.Humanoid.JumpPower = char.Humanoid.JumpPower
            num.Humanoid.PlatformStand = false
            end
            until num ~= nil or torch == max
        else
        haul.Value.Parent.Primary.Value = nil   
        end
    else
        local c = haul.Value.Parent.Players:GetChildren()
        for index, item in pairs(c) do
            if item:IsA("ObjectValue") and item.Value == char then
                item:remove()
            end
        end
    end
    haul.Value.Parent.Strength.Value = haul.Value.Parent.Strength.Value - char.Strength.Value
    haul.Value.Parent.Players.Number.Value = haul.Value.Parent.Players.Number.Value - 1
    haul.Value.Haul.Part0 = nil
    char.Humanoid.WalkSpeed = char.plrSpeed.Value
    char.Humanoid.JumpPower = char.plrJump.Value
    char.Humanoid.PlatformStand = false
    wait(.5)
    char.plrJump:remove()
    char.plrSpeed:remove()
    haul.Value.Haul.Part1 = nil
    haul.Value.Taken.Value = false
    haul.Value.Haul:remove()
    haul:remove()
end
colorChangeEvent.OnServerEvent:Connect(press)

And here is the client script

local ReplicatedStorage = game:GetService("ReplicatedStorage")
local colorChangeEvent = ReplicatedStorage:WaitForChild("Release")
plr = script.Parent.Parent.Parent.Parent.Parent.Parent
debounce = false


function buy()
    colorChangeEvent:FireServer()
    script.Parent.Parent.Selectable = false
    script.Parent.Parent.Visible = false
end

script.Parent.MouseButton1Down:connect(buy)
