Well when gets returns the string it would still contain t= he "\n" at the end of the line so you would be comparing "2\= n" to "2" which will not match. The .to_i will convert as mu= ch of the string it can into an integer. So a "2cats\n" will be c= onverted to a 2. The moment .to_i encounters a non digit it stops so the &q= uot;\n" from the "2\n" will be ignored.

Anyhow here is a quick hack on your program. It might be of some help

mainMenu =3D "Main Menu:

=A0 =A0 Phone Book Application

=A0 =A0 1.) Print Phone Book

=A0 =A0 2.) Add Entry

=A0 =A0 9.= ) Quit Application

=A0 =A0 Ple= ase select an option:"

option =3D "= ;"

while optio= n !=3D "quit"

=A0 puts mainMenu

<= /div>

=A0 option =3D gets.chomp

=A0 case option

=A0 when "1"

=A0 put= s "TODO: Print Phone Book"

=A0 when "2"

=A0 =A0 puts "TODO: Add Entry"

=A0 when "9"

=A0 =A0 puts "TODO: Quit Entry, type 'quit' t= o exit."

=A0 =A0 print ">"

=A0 =A0 option =3D gets.chomp

=A0 else

=A0 =A0 puts "Error, plea= se enter 1, 2, or 9. (you entered #{option})"

=A0 end

end
