For i,v Loop not firing?

SG=game.Players.LocalPlayer.PlayerGui
Main=SG.DDR.Main

for i,v in pairs(Main.Left:GetChildren()) do
    print 'cat'
    if v.Position.Y.Scale ==-0.2 then
        v:remove() Lv=Lv+1
    end
end 

The Code wont fire. I put in print 'cat' to see if it'll at least fire but it doesn't. Where did I go wrong?
