Working on this for a while

Been working on this for a while. Have comb through it several times. Can you please help me?

Thank you.

   **Your code so far**
let count = 0;

function cc(card) {
 switch(card)  {
   case 2:
   case 3:
   case 4:
   case 5:
   case 6:
     count++;
     break;
   case 10:
   case "J":
   case "Q":
   case "K":
   case "A":
     count--; 
     break;

}

var holdbet = 'Hold'
if (count > 0) {
  holdbet = 'Bet'

}

return count + " " + holdbet;

}

cc(2); cc('K'); cc(10); cc('K'); cc('A'); 
console.log(cc(4))
