**my code won’t pass no matter what I do

Your code so far
let count = 0;

function cc(card) {
// Only change code below this line
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 action = ‘’;
if (count > 0){
action = ‘Bet’;
} else {
action = ‘Hold’;
}
return count + “” + ‘Bet’;

// Only change code above this line
}

cc(2); cc(3); cc(7); cc(‘K’); cc(‘A’);

let 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;
  }
  var action = '';
  if (count > 0){
    action = 'Bet';
  } else {
    action = 'Hold';
  }
return count + "" + action;
  
  // Only change code above this line
}

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

Preformatted textstill not passing

Here

And here

What are these lines doing? They are not changing the value of count

Here, what is the "" doing? That’s an empty string, so it isn’t adding anything to the returned value.

Hi there. Your count increment assignments are wrong. Should be count = count + 1 and same for decrement. Right now count isnt changing. Hope this helps
