I can't give over for this step......

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

var userName = "variable";

console.log(id.length); console.log(id.toLowerCase()); console.log(id); console.log(id.toUpperCase());

console.log(lastName.toUpperCase());

...using string concatenation so that the final value of userName is "23188XTR#SMITH"

Can I help me? Thanks....

Hey Massimo,

That challenge is asking you to combine the values of the id and lastName variables using a # and store the result in a new variable called username, like this:

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

var userName = id + "#" + lastName; // this evaluates to "23188XTR#SMITH"

...OPS...this is the new message (Bummer!): Did you call 'toUpperCase()' on 'LastName'? Why?

It's because the last name needed to be in all caps, per the instructions. You do that like this:

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

var userName = id + "#" + lastName.toUpperCase(); // this evaluates to "23188XTR#SMITH"
