Subject: How to pass established/defined arrays into def method.

I am trying to pass a defined array into a method. Ruby is interpreting
it as an undefined local variable. Is there a way around this? Also, can
a def method take a string and an array as parameters?

player1 = [ ["Ten", 10, "Hearts"], ["King", 13, "Clubs"], ["Queen", 12,
"Clubs"], ["Three", 3, "Clubs"], ["Ten", 10, "Clubs"], ["Jack", 10,
"Clubs"], ["Ten", 2, "Diamonds"] ]

def check_for_flush(suit, player)
  occurrences_of_suit = 0
  player1.each do |subarray|
          if  subarray[2].downcase == "#{suit}"
    occurrences_of_suit += 1
    end
  end

suit_hand = []
  if suit >= 5
    $player1.each do |subarray|
      if subarray[2] == "#{suit}"
        suit_hand << subarray
      end
    end
  end
        puts suit_hand.inspect
end

check_for_flush ('Clubs' )
check_for_flush ('Spades' )
check_for_flush ('Diamonds')
check_for_flush ('Hearts')

# I would also like to create a parameter player so that I can load
different arrays into the method.
