Tell us what’s happening:
I couldn’t run the code. Please help me out finding the error.

Your code so far


var 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:
    count += 0;
    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
}

// Add/remove calls to test your function.
// Note: Only the last will display
cc(2); cc(3); cc(7); cc('K'); cc('A');

I suspect that there should be a space between the count value and the string.

3

Sorry but which line you are talking about? I am not able to find it.

4

Your return statements.

Hi
I dont get it why my code isn’t working

function cc(card) {
// Only change code below this line
if(card>1 && card<7)
count += 1;
else if(card>6 && card<10)
count += 0;
else
count -= 1;

if(count>0)
return count+“Bet”;
else
return count+“Hold”;

// Only change code above this line
}

Welcome to the forum! And you are really close to solving this!

When I copy-paste your code into the challenge the Double quotes ( " ) are causing an error. Try to use Single quote ( ’ ).

Then you’ll just want to compare your result, (5Bet) to the test expected result (5 Bet)
