Script not working

I have made a viewmodel and wanted it to sway using Hook’s Law and following @EgoMoose VIdeo on the topic.

I ended with the following scipt that doesnt work at all. Instead it rotates the viewmodel as i rotate the camera. I have no errors or warns in the output.

RunService.RenderStepped:Connect(function(deltaTime)

        local Current, Velocity, Target  = WeaponViewmodel.PrimaryPart.CFrame.LookVector, Vector3.new(), camera.CFrame.LookVector
        local AngleMaxDistance = 0.15
        
        deltaTime *= 60
        
        local k, friction = 0.005 * deltaTime, 0.175
        local PrimaryPartCFrame = WeaponViewmodel.PrimaryPart.CFrame
                
        local Distance = (Target - Current) 
        
        local Force = Distance * k
        Velocity  = (Velocity * (1 - friction)) + Force
        
        local pos = Current + Velocity
        
        SwayCFrame = CFrame.new(pos)
       WeaponViewmodel:SetPrimaryPartCFrame(camera.CFrame * MainCFrame * AimingCFrame * BobbleCFrame * SwayCFrame)
end)

If anyone could help me figuring out what I am doing wrong please, thanks !
