How do you make it move y axis down ?

As the title says if i edit the numbers in the angles it doesn't work. Help me don't change this script thx!

val = script.Parent.Parent.Open
val2 = script.Parent.Parent.Moving
DA1 = script.Parent.Parent.DoorA1
S1 = script.Parent.Beep
Open = script.Parent.Parent.SoundPlayer.Open
Close = script.Parent.Parent.SoundPlayer.Close
function onC()
S1:Play()
if val2.Value == false then
if val.Value == false then
val2.Value = true
Open:Play()
for i = 1, (DA1.Size.X*3.50)-3.50 do
wait(0.01)
lv = DA1.CFrame
DA1.CFrame = lv + ((lv*CFrame.Angles(0,math.pi/2,2)).lookVector*0.25)
end
val2.Value = false
val.Value = true
else
val2.Value = true
Close:Play()
for i = 1, (DA1.Size.X*3.50)-3.50 do
wait(0.01)
lv = DA1.CFrame
DA1.CFrame = lv - ((lv*CFrame.Angles(0,math.pi/2,2)).lookVector*0.25)
end
val2.Value = false
val.Value = false
end
end
end
script.Parent.ClickDetector.MouseClick:connect(onC)
