how is a print messing up a localscript? [answered]

I had a localscript, it worked fine, i added one print statement -print('test)'- then it didnt work, i removed the print, it didnt work again, i havent done anything to that script just added something to print and it didnt work again!

while wait(.5) do
    if math.sqrt((math.pow(script.Parent.badcirc.Position.X.Scale-script.Parent.circ.Position.X.Scale, 2))+(math.pow(script.Parent.badcirc.Position.Y.Scale-script.Parent.circ.Position.Y.Scale, 2))) <= 0.12 and game.Players.LocalPlayer.Leaderstats.Pass == false then
        print('nothing') --it worked before, now it doesnt, well i had something else here it worked but it didnt after i added this
    end
end
