Using the score counter in the Ultimate quiz Challenge

I am trying to get the score to update with every correct answer. I must have my var score in the wrong place but don't know how to use it correctly yet. any help would be appreciated. Thank you

This is an example link

/* 
This is a quiz to test the ability of
the program to keep score and award
a badge to the player at the end
*/


//This block of variables establishes the initial conditions of the answers
var correctAnswerOne = false;
var correctAnswerTwo = false;
var correctAnswerThree = false;
var correctAnswerFour = false;
var correctAnswerFive = false;

// This is the score counter which will keep track of the points throughout the game.
var score = 0
document.write(score);

// This is the start of the Questions

//This is the first block of code
var answerOne = prompt("What is the capital for the state of Washington?");
if (answerOne.toUpperCase() === 'OLYMPIA') {
  alert("Great! You guessed right!");
  if (answerOne.toUpperCase() === 'OLYMPIA') {
     correctAnswerOne === true;
  if (correctAnswerOne === true ) {
    document.write(score += 1);
        }  
    }
} else {
  alert("OOOO! I am soooo sorry but that is not right. The right answer is Olympia");
  }



// This is the second block of code (Which I haven't done yet.
var answerTwo = prompt("What is the past tense of drink");

There are some issues with the program logic, in this section:

if (answerOne.toUpperCase() === "OLYMPIA") {
  alert("Great! You guessed right!");
  if (answerOne.toUpperCase() === "OLYMPIA") {  // duplicate test
    correctAnswerOne === true;                  // assignment needed here
    if (correctAnswerOne === true) {            // test not needed
      document.write((score += 1));             // extra parentheses
    }
  }
}

Note that the 2nd "if" test is identical to the first, so it is not needed and can be removed. Then, on the next line there's a comparison operator ("===") but an assignment (=) was probably intended. Finally, the third test won't be needed once the assignment correction is made, because it only tests for the condition created by the assignment.

So that whole section can be condensed to:

if (answerOne.toUpperCase() === "OLYMPIA") {
  alert("Great! You guessed right!");
  correctAnswerOne = true;                  // only needed if you will use it later
  document.write(score += 1);
}

Thank you so very much. This works so much better and is much cleaner than my origial code. You're a life saver. Kind regards Mr. Steven Parker.
