Hello Raj,

I believe the only issue is that you have "" + firstName on the second line. You only need firstName + to append a string to the end.

I hope this helps.

:point_right: You did well appending " rocks!", but...

Appending an empty string in front of your name serves no purpose. And while in actual practice it would do no harm either, in this case it is confusing the challenge checker.

Thanks for the reply. Actually I solved this error already but forget to update the question here. BTW thanks again.
