Help, I am not sure what I am messing up. 1st time learner here.

Keeps saying the I didn't add the '#' between 'id' and 'lastName'.

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

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

Hi Ryan. I think it wants you to do everything on one line. Also, you don't need parentheses around your variable names.

So something like

var userName = upper case id + hash tag + upper case last name;

You need to apply toUpperCase() to post the id variable and the lastName variable while doing the assignment to the userName variable and not putting it all together and then doing toUpperCase() on it.

Hi Ryan,

The challenge wants you to turn the # symbol into a variable. Try using this :

var id = "23188xtr";

var lastName = "Smith";

var hash = '#';

var userName = id.toUpperCase() + hash + lastName.toUpperCase();

this is what you need to do in the first step ```var id = "23188xtr"; var lastName = "Smith";

var userName = id.toUpperCase ();

// the second step should look something like this 
var id = "23188xtr";
var lastName = "Smith";

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

remeber when you are calling a function like the toUpperCase you must include () i can further exsplain what exactly this code means if you would like a more indepth review

inside the var userName you are calling the var id and using the function toUpperCase() to change the value of id to all uppercase then you are concatenating that var by adding + with the string "#" and concatenating again with another

  • to the var lastName witch you called the same function of toUpperCase() on
