Counting Cards struggle

Tell us what’s happening:
I don’t understand why my code is not working. I need your help :frowning:

Your code so far


var count = 0;

function cc(card) {
  // Only change code below this line
  switch (card){
    case 2:
    case 3:
    case 4:
    case 5:
    case 6:
    count = +1;
    break; 
    case 10:
    case 'J':
    case 'Q':
    case 'K':
    case 'A':
    count = -1;
    break;
  }
  if (count <= 0){
    return count + "Hold";
  } else {
    return count + "Bet";
  }
  return "Change Me";
  // Only change code above this line
}

// Add/remove calls to test your function.
// Note: Only the last will display
cc(2); cc(3); cc(7); cc('K'); cc('A');
