I have an error in Ruby in the biller app. I am getting an error with unexpected characters in a scope designation.

Here is the line of code as presented in the Scope video:

scope :starts_with, -> (letter) { where("name LIKE ?", letter + "%") } - caused a lot of errors

I changed it to - scope :starts_with, -> letter { where("name LIKE ?", letter + "%") } and it works. Does anyone know why?

Here is the full code from the 'customer.rb' file that actually seems to work, where the one with the () around 'letter' does not:

class Customer < Account has_many :time_entries scope :premier, -> { where("employees> ?", 30)} scope :newest, ->{ order("created_at DESC")} scope :starts_with, -> letter { where("name LIKE ?", letter + "%") } end

Thank you for your help!
