Counting Cards - NEED HELP

Can someone tell me why this isn’t working through? After I couldn’t get it, I copied the solution verbatim and it still doesn’t work. Let me know what you guys think? Thank you so much!

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:
    case 10:
    case 'J':
    case 'Q':
    case 'k':
    case 'A':
  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');

case 'K': your K should be capital.
