Are my player rotation scrpits broken?

Hey, i have a weird problem

sometime ago i made these scripts that worked, but now they don't, i wasn't changing anything in them

Scripts:

local waist = script.Parent:WaitForChild("UpperTorso"):WaitForChild("Waist")
local ev = script.Parent.Camera

function answears(plr,newLook)
	waist.C0 = waist.C0:lerp(CFrame.new(waist.C0.p) * newLook, 0.1)
end

ev.OnServerEvent:Connect(answears)

local chr = script.Parent local waist = chr:WaitForChild("UpperTorso"):WaitForChild("Waist") local ev = chr.Camera

function fire() local look, origin = game.Workspace.CurrentCamera.CFrame, chr.HumanoidRootPart.CFrame look = look:ToWorldSpace(CFrame.new(0, 1.5, 0)) local x,y,z = look:ToEulerAnglesXYZ() local rx,ry,rz = origin:ToEulerAnglesXYZ()

x = math.clamp(x, -72, 72)
local newLook = CFrame.Angles(x,y,z)
local newOrig = CFrame.Angles(rx,ry,rz)
newLook = newOrig:ToObjectSpace(newLook)

ev:FireServer(newLook)
waist.C0 = waist.C0:lerp(CFrame.new(waist.C0.p) * newLook, 0.1)

end

game:GetService'RunService'.RenderStepped:connect(fire)

btw, i also have an event named Camera, all of these things are in StarterPlayerScripts folder

I have no idea what a "scrpit" is.
