toUpperCase() is a function so it does not suppose to be in quotes, the same with id because it is a variable

so that specific point suppose to be written as

var userName = id.toUpperCase()

it has to do with syntax.

You are welcome Agnes Caringal :)

how about if I combine to variables using #

Can you give an example of that?

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 the userName is "23188xtr#smith"

this is my answer:

var UserName = id.toUppercase() "#" lastName.toUpperCase();

but when I run my code, like....Opps! it looks like task 1 is no longer passing

You need to use the + sign to concatenate.

I mean... +"#"+ ...
