Why wont this else if code work to add "poison" and "star"? It seems the same on the video, but it isn't running.

// when the player collects an item on the screen
function itemHandler(player, item) {
  item.kill();
  currentScore = currentScore + 10;
  } else if (item.key === 'poison') {
     currentScore = currentScore - 25; 
  } else if (item.key === 'star') {
     currentScore = currentScore + 25;
  }
  if (currentScore === winningScore) {
      createBadge();
  }
}

It would be nice if you could format your code. As it stands, it's hard to read.

Hi, I think you mess up the brackets. There should be an even number of them in the code. Apparently, you have nine of them. Second of all, you should have an if statement before all those else-if statements. Hope this helps.

Sorry, I am very new to coding. I am not sure how to format it in a post. It looks like the same JS format when I post the question though. How do I make it less condensed?

You can post your code within three backticks. Backtick is the key (generally) above your tab key - `

There is also a "markdown cheatsheet" beneath the textbox where you type your posts, you can refer that too.

Code Wrap your code with 3 backticks (```) on the line before and after. If you specify the language after the first set of backticks, that'll help us with syntax highlighting.

      ```html
      <p>This is code!</p>
      ```

Thank you. It has been updated. I moved on in the course, but I still never got the code to work. Could one extra space make it not run? I am wondering if it was a browser issue?

Hello. I don´t know what your code is supposed to do but our brackets is a mess. Try this:

function itemHandler(player, item) { item.kill(); currentScore = currentScore + 10;

if (currentScore === winningScore) { createBadge(); } else if (item.key === 'poison') { currentScore = currentScore - 25; } else if (item.key === 'star') { currentScore = currentScore + 25; } }

That should work.
