Finally, add a # symbol and lastName in uppercase to the end of the userName string. The final value of userName is "231

I don't understand why the result is 23188STR#SMITH...

var id = "23188xtr"; var lastName = "Smith";

var userName = id + "#" + lastName.toUpperCase( );

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

var userName = id + "#" + lastName.toUpperCase( );

you are almost there, just called toupperCase method on id, as Jonathan mentioned

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

Try adding toUpperCase() to the ID variable as you had it for the first part. This is what makes every part of the string you'll make uppercase. The id, is no longer being transformed into uppercase.
