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

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

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

Hey Stellah Avanthi,

You’re so darn close! Take a look at id.toUpperCase() and lastName.toUpperCase(). Anything inside of double quotes is considered a string in this scenario. Take a look at it and see if you can figure it out, and if you need more help let me know!

Good luck!
