Issue with my ruby code

def score(a, b, c, d, e)
    puts "#{a},#{b},#{c},#{d},#{e}"
  if a == 'D'
    puts "Right Answer"
    s = 1
  else
    puts "Wrong Answer"
  end
  if b == 'W'
    puts "Right Answer"
    s2 = s+1
  else
        s2 = s
    puts "Wrong Answer"
  end
  if c == 'B'
    puts "Right Answer"
    s3 = s2+1
  else
        s3 = s2
    puts "Wrong Answer"
  end
  if d == 'P'
    puts "Right Answer"
    s4 = s3+1
  else
        s4 = s3
    puts "Wrong Answer"
  end
  if e == 'L'
    puts "Right Answer"
    s5 = s4+1
  else
        s5 = s4
    puts "Wrong Answer"
  end
    puts "your score is #{s5}"
end

A1 = gets
puts "capital of USA?"
A2 = gets

A3 = gets
puts "capital of france?"
A4 = gets
puts "capital of UK?"
