HELP,EM STUCK GUYS

Complete the assignment to the userName variable by adding a # symbol followed by an all uppercase version of the lastName variable. In other words, using string concatenation so that the final value of userName is "23188XTR#SMITH" var id = "23188xtr"; var lastName = "Smith"; var userName

app.js 
var id = "23188xtr";
var lastName = "Smith";
var userName="id".toUpperCase();
var userName="23188xtr"+"SMITH";

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

//+dont put 'id' in quotes
//var userName="id".toUpperCase();

//+In the previous step you should have used:
//var userName = id.toUpperCase();

//+dont define userName twice with var
//+use the variables, don't make new strings
//+you forgot to add the # symbol
//+you did not assign the correct value.  # sign missing, "xtr" still lowercase
//var userName="23188xtr"+"SMITH";

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

I see few errors in your code

var id = "23188xtr";
var lastName = "Smith";
var userName="id".toUpperCase(); // don't add quote around the var.... this is now a string not a var anymore
var userName="23188xtr"+"SMITH";

You goal here to use the toUpperCase() on both id and lastName var. The toUpperCase() method turns all letter to a capitalize letter. Like this

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