    <!DOCTYPE html>
    <html>
    <body>
    <button onclick="theFunction3()">Click here to start le quiz</button>
    <p id="q"></p>
    <script>
    function theFunction3()
    {
    var x=Math.floor((Math.random()*20)+1);
    var y=Math.floor((Math.random()*20)+1);
    var score;
    var attempt;
    var Tattempt=sum(attempt)

    if (Tattempt<11)
    {
    prompt(x + "x" + y + "=?","");
    var name=prompt(x + "x" + y + "=?","");
    if (name=x*y)
    {
    score=1;
    attempt=1;
    }
    else if (name!=x*y)
    {
    score=0;
    attempt=1;
    }
    else
    {
    var z="You've got" + sum(score) + "Out of 10!";
    document.getElementById("q").innerHTML=z
    }
    }
    }
    </script>
    </body>
    </html>

    1. Please state any errors in this code. (If any)
    2. I want to create a math quiz on multiplication using JavaScript. Questions are to be randomly generated and separately displayed in a prompt box. The user must recieve a score out of ten. A prompt box for the result is optional.

    Welcome to DevShed Forums, qwertyoone.

    This wouldn't happen to be a homework assignment would it?

    What is the purpose of the "sum" function?

    Why do you use prompt() to ask the same question twice?
