Counting Cards - error

Tell us what’s happening:

Why is my code not working?

Your code so far


var count = 0;

function cc(card) {
  // Only change code below this line
  var count = '';
  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;
  }
   if (count <= 0){
       return count +' Hold';
      } else {
       return count +' Bet';
      }
}

  // 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');

Hi,
The challenge asks to manipulate the global variable var which is already pre-defined above the function, so you have to operate on that variable. :slight_smile:

Your ‘count’ variable inside the functions overwrites the global ‘count’ variable
