Hi there Simsima! I've taken a look at your code and there's just a few syntax errors that are preventing your code from running. The first thing you're going to want to do is to look at line 6 where you're defining correctAnswer. You'll want to make sure to put the ; at the end of the line.

The next thing to look at is line 54 where you've written an in-line comment. You have the right idea, but the wrong slash! You'll want to change those from back-slashes \\ to forward-slashes //.

The last syntax error you'll need to change is at lines 76 and 78. Even though it's the last conditional, it still needs curly brackets. Writing your code as follows will fix that error:

} else {
  rank = `No Crown`;
}

The above changes will remove the errors that are blocking your app from running! There is one more error, but it's in how the program is ranking the players. I'll leave this one to you to figure out! Just look back over the directions and how many correct answers it takes to get the different rankings ;)

Hope this helps!

When debugging via the console log it is incrementing once the first response is given with 'yes' response. Even it if do not input anything it seems the logic is to increment.

i don't understand what is going on ?

I placed the console outside the conditional as well. 

const q1 = prompt(` Are multi-line comments started and ended with " /* */ " `);

if (q1.toUpperCase() === 'YES' || q1.toUpperCase() === 'Y'){
  correctAnswer +=1;

} 
console.log(correctAnswer);

thank you for your time
