I have tried this in many different ways…they are starting to scramble my brain. Can someone please help me. What I have now is word by word how it is on the help video…and still its wrong.

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 10:
case "J":
case "Q":
case "K":
case "A":
count--;
break;
}
var holdbet = "Hold"
if ( count > 0) {
holdbet = "Bet"
 }
return count + "" + holdbet;
// Only change code above this line
}

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

If you add

console.log(cc());

at the end of your code, I think that you’ll be able to see the issue. You have a missing space between the number and the Hold/Bet string.

I wrapped a function call in a console.log - take a look at what you are returning. Does something seem off here? :slight_smile:

I have and it comes up 1Bet, I changed the code and am still getting the same thing…I couldn’t find a missing space.

  }
  if (count > 0) {
    return count + " Bet";
  } else {
    return count + " Hold";
  }

This is what I replaced it with. This is what is on the hint…still does not work. can you give me a more direct hint.
Thanks

When I make that change, your code passes for me. Can you post your full code?

I’ve edited your post for readability. When you enter a code block into a forum post, please precede it with a separate line of three backticks and follow it with a separate line of three backticks to make it easier to read.

You can also use the “preformatted text” tool in the editor (</>) to add backticks around text.

See this post to find the backtick on your keyboard.
Note: Backticks (`) are not single quotes (’).

```var count = 0;

  // Only change code above this line
}

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

In the above version, you don’t have the spaces you added in this snippit.

I don’t understand. My first code had a completely different end and you said I had missing space. It was exactly like the watch video hint. So I chanced it to be be exactly like the hint version…neither are working. I cant understand it. The tree that are now the if statement are completely that same. I don’t see the spaces. Please help.

This

is not this

Your snippet and your code you posted don’t agree.

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 10:
  case "J":
  case "Q":
  case "K":
  case "A":
  count--;
  break;
} 
var holdbet = "Hold"
if (count > 0) {
  holdbet = "Bet"
} 
  return count + "" + holdbet;
}



  // Only change code above this line
}

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

You still are missing a space. This looks like your first version.

There is no space in between those two quotes.

It happens to all of us :slight_smile:

I didn’t know I needed a space after the " … so that you.
:laughing:

if you need a space in the final result, you need to add it somewhere, they do not magically appear

I’m sure you will remember next time!

Happy Coding!
