The challenge error message give a clue to the first issue: "Can't find first_and_last_4". If it were due to a syntax error you would get "Bummer!". This error means the code compiles correctly but the function isn't found. :point_right: time to check for spelling errors!

Fixing the spelling error, the code isn't correct. Since you've pass Task 1, you should know how to find the last 4 characters. Using this knowledge you can combine the two solutions using string concatenation by including a + sign.

Post back if you need more help. Good luck!!
