I simply don't know what else to try. My conditional if statement isn't working for some reason, even though the values are equal...

    @input = gets()
    s = "List"

    if @input == s
      puts "You typed in List" #This code is NEVER reached
      list()
    else
      puts s + " " + @input
    end

I'd really appreciate some help. I shouldn't have such a problem in a language like Ruby.

The problem is your input contains a newline. The actual value of the input is "List\n".

Try using @input = gets.chomp to remove the newline - it should work then.
