Hi there! It seems like you understand concatenation so I'm just going to give this hint. You can concatenate multiple strings like so:

variable1 + "#" + variable2;

I feel confident that you can get it with this hint, but let me know if you're still stuck! :sparkles:

You have to concatenate both variables (id + lastName) with ('#') in the middle, like this: var userName = id.toUpperCase() + "#" + lastName.toUpperCase();

why do I frequently get this error? I keep returning and entering task 1, and it will never accept my answer for task 2.
