  alert(input.value);
});

Hi Wojciech,

I copied exactly what you had into the challenge and it passed just fine. Something must have happened on the server side. Try it again if you haven't already.

Hope this helps.

thank you, yes sometimes there might be an issue with the server :) confusing, since I am beginner I never know if I am doing something wrong or is it just temporary malfunction. Thank you for your attention anyway.

happy coding, W
