What is wrong with my function?

Every time I run through my code the function does not continue passed the first if statement. Even when players has values it still won't continue. I have even tried changing

players

to

players[1]

Here's the code:

playersService = game:GetService("Players")
ServerScript = game:GetService("ServerScriptService")

function testPlayerDeath()
	local players = playersService:GetChildren()
	if players == not nil then
		print("if done")
			for _, players in pairs(players) do
				script.ChildAdded:connect(function()
					print("passed")
					if script:FindFirstChild(players.Name) == players.Name then 
						print("passed2")
						local Value = script:WaitForChild(players)
						if Value.Value == true then
							print("passed3")
							print("Current Selection: "..players)
							onPlayerDeath(players)
							failed = false
							return failed
						else
							failed = true
							return failed
						end
					end
				end)
			end
	else
		failed = true
		return failed
	end
end


while true do
	wait()
	testPlayerDeath()
	print("failed?: ")
	print(failed)
end

if you find anything confusing or wrong in my code please leave a comment.

edit: the use of the return is simply for debugging

Even when corrected, the first if statement has no purpose being there. Checking if a player exists, even though you're referencing it directly from the PlayerService, is useless.
