I did it like this

var quiz = [["What is my name?", "George", ""], ["What is my wife name?", "Dina", ""], ["What is my son name?", "Chris",""], ["What is my father name?","Emil",""], ["What is mother name?","Aida",""] ]; var correctAnswers = 0; var html = ""; var html2 = "";

html = "<ol>"; html2 = "<ol>";

for (i = 0; i < quiz.length ; i++){ quiz[i][2] = prompt (quiz[i][0]); if (quiz[i][1].toLowerCase() === quiz[i][2].toLowerCase()){ html += "<li>" + quiz[i][0] + "</li>" correctAnswers += 1; }else{ html2 += "<li>" + quiz[i][0] + "</li>" }; }

html += "</ol>"; html2 += "</ol>";

document.write("<h3>You got " + correctAnswers + " question(s) right</h3>");

document.write("<h2>You Got these question(s) correct:</h2><br>"); print(html);

document.write("<h2>You Got these question(s) not correct:</h2><br>"); print(html2);

function print(message) { document.write(message); }

var quiz = [["What is my name?", "George", ""], ["What is my wife name?", "Dina", ""], ["What is my son name?", "Chris",""], ["What is my father name?","Emil",""], ["What is mother name?","Aida",""] ]; 
var correctAnswers = 0; 
var html = "<ol>"; 
var html2 = "<ol>";

for (i = 0; i < quiz.length ; i++){ 
    quiz[i][2] = prompt (quiz[i][0]); 
    if (quiz[i][1].toLowerCase() === quiz[i][2].toLowerCase()){ 
        html += "<li>" + quiz[i][0] + "</li>"; //semicolon missing
        correctAnswers += 1; 
    }else{ 
        html2 += "<li>" + quiz[i][0] + "</li>"; //also missing
    } 
}

html += "</ol>"; 
html2 += "</ol>";

document.write("<h3>You got " + correctAnswers + " question(s) right</h3>");

document.write("<h2>You Got these question(s) correct:</h2><br>"); 
print(html);

document.write("<h2>You Got these question(s) not correct:</h2><br>"); 
print(html2);

function print(message) { document.write(message); }

Use "" on one line before you enter a code in the forum, and another "" again on a single line after the code so that the snippet is more readable. Now your code has typos: missing semicolons and I think a { bracket. Don't try to write everything at once - write test write test so that you can find your mistake. Test your code in a real environment to see the errors. I did not mess up the code much but in the beginning, you declare a variable and its empty, on the next two lines you give them values, there is no point in that. :)
