var id = "23188xtr";
var lastName = "Smith";
var userName = id.toUpperCase();
Because id is a string, it inherits the methods that the String object has...so any of the methods that work on a string will work on the id variable...It's asking you to then take the uppercase version and store it into a new variable..username (which it provided)...
The 2nd part of the challenge asks you to add a # in between an uppercase version of the lastName variable and store it back into the userName variable.. it wants you to concat this together...:
userName = userName + '#' + lastName.toUpperCase();
you have to add quotes around the # to turn it to at string, concatenated with the lastName variable with the toUpperCase() method...hope this explanation helped!! If you have any other questions, don't be afraid to ask!
Happy Coding!

13,010 Pointsafter reviewing the video to understand what you are learning, the second part of the challenge could be coded like it was in the video,
userName += '#' + lastName.toUpperCase();the userName variable doesn't have to be used again...the += operator will take whats on the left side, add to it, and automatically bind it back to userName...both answers work, this one is just a little bit shorter and more conventional..the first example shows you a little bit better of what is going on.
Just remember that whatever is contained in a variable is still the type of object it was...almost like a placeholder...so what ever you and do to that type of object, you can do to the variable holding that object! Keep working at it!
