Tell us what’s happening:
can’t i use multiple case like these?

Your code so far


var count = 0;

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

return "Change Me";
// Only change code above this line
}

cc(2); cc(3); cc(7); cc('K'); cc('A');
