Camera script suddenly not working but was before?

I made this script and it was working fine before. Only added a few variables so I could edit it more freely. Suddenly the camera stopped moving. It goes to the correct first position, but then it won't move like it is supposed to.

Any support? I have checked all the variables and locations of the values and they are all correct.

Here is the code below.

wait()
foc = script.Parent.camFoc.Value
camPos = script.Parent.camPos.Value
speed = script.Parent.camSpeed.Value
pos = script.Parent.camPosTwo.Value

while true do
	pos = script.Parent.camPosTwo.Value
	foc = script.Parent.camFoc.Value
	camPos = script.Parent.camPos.Value
	speed = script.Parent.camSpeed.Value
	game.Workspace.CurrentCamera.CoordinateFrame = CFrame.new(script.Parent.camNumber.Value-14.2, 31.5, -pos)
	game.Workspace.CurrentCamera.CameraType = "Fixed"
	game.Workspace.CurrentCamera.FieldOfView = "60"
	game.Workspace.CurrentCamera.Focus = CFrame.new(camPos,0,foc)
	speed = script.Parent.camSpeed.Value
	pos = pos + speed
	foc = foc + speed
	wait()
end
