I dont know what Im doing wrong, can someone help me?
That looks like an old error message from when the exercise had four variables (first_name used to be included). It may now relate to the extra, unasked for code,
Remove those three lines and your code should pass.
Try a page refresh (not reset) and submit again. I don't see a problem in what you have.
I also had to put my last name, eventhough the it was not mentioned in the question
I have a same problem!
Try creating a first_name variable, as well.
Thanks man very helpful
