IsAlive a nil value?

[Triple-X]

I keep trying to use this check to make sure the ply is alive before paying him and I keep getting IsAlive as a nil value dont know why. The file is a shared.lua.

if PAYDAYS then
		timer.Create( "payday_timer", PAYDAY_INTERVAL, 0, function()
			for k, ply in pairs(player.GetAll()) do
				if ply:IsAlive() then
					ply:Money_Add( PAYDAY_AMOUNT )
				end
				if PAYDAY_SOUND then
					ply:EmitSound("tools/ifm/beep.wav")
				end
			end
		end )
	end

I also trying !ply:IsAlive in a different way as an alternative and still nothing.

Edit:
Im an idiot, ply:Alive. Thanks anyways.
