Why I get "Oops! It looks like Task one is no longer passing"?

This is my input...

var fullName = document.getElementById("full_name"); var lastName = document.getElementByClassName("last_name");

It should be .getElementsByClassName. getElementById is the only DOM selector I can think of that uses a singular 'Element'. Everything else uses 'Elements'. It's a little confusing until you thing about what you might be selecting. Id's must be unique, so you are only going to get one element returned when you select it, therefore getElementById makes sense. There could be any number of elements returned when you select based on a class identifier though, so this selector uses the plural elements getElementsByClassName.

Edit: I just checked out this challenge and it might not pass using getElementsByClassName. You might need to make the selection based on the tag name and use an offset to get the correct element... just a hint...

Thank you very much, there were 2 issues actually: as you said, the first one was about getElementsByClassName and the second one was about using getElementsByTagName. I passed the challenge :)
