Counting Cards----where is wrong?help!

Tell us what’s happening:

Your code so far

var count = 0;

function cc(card) {
  // Only change code below this line
 if (card == 2 ||card == 3 ||card == 4 ||card == 5 ||card == 6 ){//alert("2 3 4 5 6);
   count += 1;
 } else if(card == 7 ||card == 8 ||card == 9 ){
   count += 0;
 }else if(card == 10 ||card == "J" ||card == "Q" ||card == "K" ||card == "A" ){
   count -= 1;
 }
  if(count <= 0){return String (count) +"Hold";
    
  }
  else {
    return String (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');
