Build a Bank Account Class def to_s "Name: #{name} , Balance: #{sprintf("%0.2f", balance)}" end

Question

Implement a to_s method on the BankAccount class that displays the name and balance in the following format (without brackets): Name: [name], Balance: [balance] It is not necessary to use the sprintf method to implement the balance printing.

Why this is not working ?

bank_account.rb

class BankAccount
  attr_reader :name

  def initialize(name)
    @name = name
    @transactions = []
    add_transaction("Beginning Balance", 0)
  end

  def balance
    balance = 0
    @transactions.each do |transaction|
      balance += transaction[:amount]
    end
    balance
  end

  def debit(description, amount)
    add_transaction(description, -amount)
  end

  def credit(description, amount)
    add_transaction(description, amount)
  end

  def add_transaction(description, amount)
    @transactions.push(description: description, amount: amount)
  end

  def 
    to_s "Name: #{name}, Balance: #{sprintf("%0.2f", balance)}"
  end
end

  def 
    to_s "Name: #{name}, Balance: #{sprintf("%0.2f", balance)}"
  end

You put the name of the method inside the definition. Please move to_s next to the def keyword, not under it and it should work.
