    need help with javascript math game

    HI guys,
    I need some help with a javascript math game. The game is in the main content area of my web page.
    Im running a javascript that randomly selects 2 numbers and populates 2 divs with the numbers. i.e 1 num per div

    Im using the get element by id function to attach the random numbers to h2 tags.
    The user enters the answer into a text box and presses check answer button.
    A message box displays letting the user know the answer was correct or incorrect.

    The game just repeats from here the divs are repopulated with random numbers and so on.

    what i want to do is after the user answers the question and clicks the check answer button I want each question and the answer to populate the sidebar.
    num1 + num2 = ans
    num1 + num2 = ans
    num1 + num2 = ans
    num1 + num2 = ans

    could anybody please tell me how to acomplish this is driving me nuts trying to do it.

    Thanks,

    Post an attempt.

    You should, at least, be able to provide a layout of the problem in HTML

    Sorry guys for not providing my code:
    <script type="text/javascript">
    var $randomnumber1;
    var $randomnumber2;
    var $answer; // Answers to the questions.
    var $counter = 1;
    var $data;
    // Counter value displays 1 on press of start.


    function start_game() {
    document.getElementById('counternumber').innerHTML = $counter;
    document.getElementById('txtbox').value = ""; /*clears the textbox of any text */
    $randomnumber1 = Math.floor(Math.random()*11); /*generate random num, num entered into $randomnumber*/
    $randomnumber2 = Math.floor(Math.random()*11);

    document.getElementById('num1').innerHTML = $randomnumber1; /* will display num on screen in H3*/
    document.getElementById('num2').innerHTML = $randomnumber2;
    $answer = $randomnumber1 + $randomnumber2;
    $counter++;
    setFocus();
    }
    function check_answer() {
    var $txt = document.getElementById('txtbox'); /* gets text box entry, saves it to $txt*/
    var $value = $txt.value;
    if ($value == $answer) {
    alert('You are correct');
    //addimage();
    }
    else {
    alert('You are incorrect, the answer was ' + $answer);
    }
    document.getElementById('txtbox').value = ""; /*clears the textbox of any text */
    document.getElementById('num1').innerHTML = "";
    document.getElementById('num2').innerHTML = "";
    $randomnumber1 = Math.floor(Math.random()*11); /*generate random num, num entered into $randomnumber*/
    $randomnumber2 = Math.floor(Math.random()*11);
    document.getElementById('num1').innerHTML = $randomnumber1; /* will display num on screen in H3*/
    document.getElementById('num2').innerHTML = $randomnumber2;
    $answer = $randomnumber1 + $randomnumber2;
    document.getElementById('counternumber').innerHTML = $counter;
    $counter++;
    if ($counter > 4) {
    alert ('End of game......Thanks for playing');
    $counter = 1;
    document.getElementById('num1').innerHTML = "";
    document.getElementById('num2').innerHTML = "";
    }


    <div class="container" id="wrapper">
    <h3>Games Played = <b id='counternumber'></b> / 3 </h3>
    <div id="total">Total: <p id="sumtotal"></p></div>


    <div class="left"><h3 id="num1"></h3></div>
    <div class="plus"><img src="images/plus.png"></div>
    <div class="right"><h3 id="num2"></h3></div>


    <button onclick="start_game(); myCountDown()">Start Game</button>

    <form id="form">
    <input type="text" id="txtbox" />
    <input type="button" value="Answer" onclick="check_answer(); setFocus(); ShowResults()" />
    </form>
    </div>
