Looking to understand why this Javascript code is not concatenating strings to a variable.

Task

Finally, add a # symbol and lastName in uppercase to the end of the userName string. The final value of userName is "23188XTR#SMITH".

.js Code

var id = "23188xtr"; var lastName = "Smith"; var userName = id.toUpperCase();

userName += "#" + lastName.toUppercase();

app.js 
var id = "23188xtr";
var lastName = "Smith";

var userName = id.toUpperCase();

userName += "#" + lastName.toUppercase();

Hi Colt, you have a syntax error! You're missing a capital letter in the last line of your code... Can you spot where it should be? It really helps to open up your browser's developer tools -- they would have found the problem for you! :)
