Counting Cards 7,8,9

I wrote counting cards as a function and past all of the the test except the 7, 8 ,9 card test. It continues to return “0 Bet” and no matter how I think of changing it it still returns the same answer. Can someone please explain to me what is going on and what I am doing wring. Thank you for your time.

Your code so far


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

Thank you so much for pointing that I I have looked over that code for days trying to figure out what I did wrong. Once again thanks.
