Having problems with pointing arms to camera. [?]

So I'm trying to make a basic non-viewmodel gun kit that has the arms that point to where your camera is looking, taking the tool with themselves and thus creating an effect that points your gun to where you're looking, I found this random script that previously was made for only rotating the right arm, but I re-purposed it, unfortunately by adding the left arm I messed something up, the right arm which was added originally works fine, but the left one is going.. backwards.

Script here:

repeat wait() until workspace:findFirstChild(game.Players.LocalPlayer.Name)
wait()

local cam = workspace.CurrentCamera
local player = game.Players.LocalPlayer
local char = player.Character
local hastool = false
local armweld = player.Character.Torso["Right Shoulder"]
local armweld2 = player.Character.Torso["Left Shoulder"]
local origarmweldcf = armweld.C0
local origarmweldcf2 = armweld2.C0
local basearmweldcf = origarmweldcf + Vector3.new(0,0.25,-0.25)
local basearmweldcf2 = origarmweldcf2 + Vector3.new(0,0.25,-0.25)
local baseheadweldcf = char.Torso.Neck.C1
local heading, attitude, bank

function holdingtool()
    for _,instance in ipairs(char:GetChildren()) do
        if instance:IsA("Tool") then
            return true
        end
    end
end

cam.Changed:connect(function()  


    local sx, sy, sz, m00, m01, m02, m10, m11, m12, m20, m21, m22 = cam.CoordinateFrame:components()
    heading = math.atan2(m02, m22)
    attitude = math.asin(-m12)
    bank = math.atan2(m10, m11)

    if hastool then
        armweld.C0 = basearmweldcf*CFrame.Angles(0,0,attitude)
        armweld2.C0 = basearmweldcf2*CFrame.Angles(0,0,attitude)
    end

    char.Torso.Neck.C1 = baseheadweldcf*CFrame.Angles(attitude,0,0)

end)

char.ChildAdded:connect(function(child)
    if child:IsA("Tool") then
        hastool = true
        armweld.C0 = basearmweldcf*CFrame.Angles(0,0,attitude)
        armweld2.C0 = basearmweldcf2*CFrame.Angles(0,0,attitude)
    end
end)

char.ChildRemoved:connect(function()
    wait()
    if not holdingtool() then
        hastool = false
        armweld.C0 = origarmweldcf
        armweld2.C0 = origarmweldcf2
    end
end)
