Tell us what’s happening:

Help me find the bug I can’t pass this step…

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 7:
 case 8:
 case 9:
 break;
 case 10;
 case "J":
 case "Q":
 case "K":
 case "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');

That final return "Change Me" statement is redundant, so you should remove it.

Other than that, one reason that the challenge is not passing is that your function will return (for instance) “1Bet” or “-1Hold”, which isn’t exactly what is required. You’ll need to ensure that you add a space between the number and the text.

Also, you have a couple of syntax errors, which should be showing in the console.

  1. All of your case statements should end with a colon.
  2. Your switch statement should have an opening curly bracket.

Look at the example output:

-3 Hold
5 Bet

Would your return statment format the string exactly like the sample output?

    case 10:
    case "J":
    case "Q":
    case "K":
    case "A":
         count++;
         break;

Are you sure that’s what you want to do with count ?

Sorry, I can’t write the code for you. Instead, please ask questions about what you don’t understand in my hints above and I will clarify further.
