Tell us what’s happening:
Hello all, I´m stuck here; i´m not able to see my mistake; please some hint

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:
count= count +0; //******just to understand the logic  ******
 break;
 case 10:
 case "J":
 case "Q":
 case "K":
 count=count--;
}
 //************** ends of counting card*********/
 if(count>0){
  return count +" Hold";
 }
  else if(count<0){
    return count +" Bet";
 } else {
return count +" Hold";
 }
}
  // Only change code above this line


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

Are you sure this is what the instructions indicate?

Hello Randell you were right; I was a bad reader; I did this in order to get ok with the instruction, but the problems remains

in instructions it says Do NOT reset count to 0 when value is 7, 8, or 9 now my question to you is, what did you understand from this?

  • it’s missing “A” card
  • you should see how you are “incrementing” your counter and do that same for “decrementing” as well
  • are you sure about this?

address those changes along with what @ randel has pointed out already, and it should be alright, happy learning :slight_smile:
