Hello,
There are two mistakes, you do not want to change the line for the word “FirstLine” hence you do not need to use any escape character before the word and there is a backslash at the beginning of the word “SecondLine” in order to include it in the string you just need to escape one of the backslash before the word “SecondLine” with another backslash.
Try to read the Note statement in the challenge carefully.
Thank you.
