You're getting close, and you've got the lastName in uppercase. But the challenge said to also "add a # symbol" along with the lastName so you still need that.

And it also said to add these "to the end of the userName string". A normal assignment ("=") will replace what's already in the string, but a concatenating assignment ("+=") will add stuff to the end of the string.
