Why is saying wrong?

I did all the code right but when I get the number correct in the second try it still says that: Sorry. The number was 4. or any other number

var correctGuess = false; var randomNumber = Math.floor(Math.random() * 6 ) + 1; var guess = prompt('I am thinking of a number between 1 and 6. What is it?'); if (parseInt(guess) === randomNumber ) { correctGuess = true; } if ( correctGuess ) { document.write('<p>You guessed the number!</p>'); } else { document.write('<p>Sorry. The number was ' + randomNumber + '.</p>'); } if ( parseInt(guessMore) === randomNumber ) { correctGuess = true; } else if (parseInt(guess) < randomNumber) { var guessMore = prompt("Try again. The number I am thinking is more than " + guess); }

else if (parseInt(guess) > randomNumber) { var guessLess = prompt("Try again. The number I am thinking of is less than " + guess); } if (parseInt(guessLess) === randomNumber) { correctGuess = true; }

It looks like things are a bit out of order.

It's tough working with unformatted code, but I managed to spot a few issues anyway:

  • if the first guess is not correct, you immediately reveal the answer
  • after the first guess, you parse and test "guessMore", but that variable has not yet been created
  • only if that test fails do you ask for a second input and set either "guessMore" or "guessLess"
  • then, without checking to see which was used, you parse and test "guessLess"
  • but after that, the program ends without doing anything with the result of the last test

So you probably want to move things around, keeping in mind:

  • ask questions and get responses before testing the responses
  • ask all questions before revealing the answer
