This is what I'm typing : var userName = "id#lastName".toUpperCase(); The code should result with 23188XTR#SMITH

Unable to move forward with the last question to the string variables.

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

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

You're combining the var the wrong way. We use the + sign. By adding quote around the variable, it become a string not a variable anymore. 

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

you need to break that up into chunks. the first part asks you to change id to all upper case. so you would use 

var userName = id.toUpperCase();

then in the second part you already have the id to uppercase so you just need to add the # and the lastName. so like this 

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

just remember everytime you add to the var userName it changes it to what you just put into that variable.

hope this helps and happy coding.

Hi Katie, You're close. You just need to call the toUpperCase on each of the variables and use string concatenation to add the '#' then assign it all to the userName variable.

for example:

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