Personal Server Nil Value? Help Please!

Well the first part , game.Workspace:FindFirstChild("PSVariable"), checks if the value is true and the other checks if it's false. Meaning, no matter if the value is there or not the rest of the code won't run. So you must change part one to check if it equals false, "Or nil". Or you could just add a not to the front. Example,

if not game.Workspace:FindFirstChild("PSVariable") then
    --do stuff when value is nil
else
    -- do stuff when the value is true
end

I'm not sure if that's what you were asking but I tried. Good luck!
