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
