I am Stuck at exercise 16. There are two Problems. First: the console often writes "nil" and i don't know why.
Second: What is wrong with my code. The Exercise does not accept it but i don't see what is wrong.
Oops, try again.
It looks like you didn't include =begin. Make sure there's no space between the equals sign and the word begin!
# Kommentar =begin blablablabla blablablabla =end
