"This Mouse is no longer active"? please someone at least help me fix this

So basically i was making a gun, that if you click on the player, it shoots at them. So I made it like that but it keeps saying "
01:11:08.957 - This Mouse is no longer active 01:11:08.957 - Stack Begin 01:11:08.958 - Script 'Workspace.M4A1.Script', Line 6 01:11:08.958 - Stack End "

local MaxA = 30
local A = MaxA
local Reload = false
script.Parent.Equipped:Connect(function(mouse)
script.Parent.Activated:Connect(function()
    if  game.Players:FindFirstChild(mouse.Target.Parent.Name) then
        if A > 0 and not Reload then
            A = A-1
        elseif Reload == false then
            Reload = true
            wait(2)
            A = MaxA
            Reload = false
        end
    end
end)
end)

someone please help
