FOV Higher than 120 Code Help

game:GetService("RunService").RenderStepped:connect(function() 
    if (distort > 0.001) then
        cam.CoordinateFrame=cam.CoordinateFrame*CFrame.new(0,0,0,distort,0,0,0,distort,0,0,0,1)
        distort = distort - 0.001
    end 
end)

found this on the dev forum… Its a Camera FOV Higher than 120 script. What is the cam variable? local cam = game.Workspace.CurrentCamera didnt work… So what is it?

workspace.CurrentCamera works fine as the cam variable for me

local cam = workspace.CurrentCamera
local distort = 1
game:GetService("RunService").RenderStepped:connect(function() 
	if (distort > 0.001) then
		cam.CoordinateFrame=cam.CoordinateFrame*CFrame.new(0,0,0,distort,0,0,0,distort,0,0,0,1)
		distort = distort - 0.001
	end 
end)
local cam = workspace.CurrentCamera
local distort = 1

game:GetService("RunService").RenderStepped:connect(function() 
	if (distort > 0.001) then
		cam.CoordinateFrame=cam.CoordinateFrame*CFrame.new(0,0,0,distort,0,0,0,distort,0,0,0,1)
		distort = distort - 0.001
	end 
end)
