Im stuck with my code.. The computer is saying i did not call the movie hash but i did can someone help me?
movies = {
Memento: 3,
Primer: 4,
Ishtar: 1
}

puts "What would you like to do?"
puts "-- Type 'add' to add a movie."
puts "-- Type 'update' to update a movie."
puts "-- Type 'display' to display all movies."
puts "-- Type 'delete' to delete a movie."

choice = gets.chomp.downcase
case choice
when 'add'
puts "What movie do you want to add?"
title = gets.chomp
if movies[title.to_sym].nil?
puts "What's the rating? (Type a number 0 to 4.)"
rating = gets.chomp
movies[title.to_sym] = rating.to_i
puts "#{title} has been added with a rating of #{rating}."
else
puts "That movie already exists! Its rating is #{movies[title.to_sym]}."
end
when 'update'
puts "What movie do you want to update?"
title = gets.chomp
if movies[title.to_sym].nil?
puts "Movie not found!"
else
puts "What's the new rating? (Type a number 0 to 4.)"
rating = gets.chomp
movies[title.to_sym] = rating.to_i
puts "#{title} has been updated with new rating of #{rating}."
end
when 'display'
movies.each do |movie, rating|
puts "#{movie}: #{rating}"
end
when 'delete'
puts "What movie do you want to delete?"
title = gets.chomp
if movies[title.to_sym].nil?
puts "Movie not found!"
else
movies.delete(title.to_sym)
puts "#{title} has been removed."
end
else
puts "Sorry, I didn't understand you."
end
This is my code

As they said in the instructions, there's no need for to_sym or to_i yet. If you take them out it should pass.

Also, this looks a lot like the code given as an example at the beginning of the lesson, you're not going to learn if you just copy paste code, try to come up with your own, you're only making it harder for yourself. Good luck for the rest of the course.

you should test it out by adding a movie
