    Default code not returning sum

    Hello. Writing Java is new to me, and I've been reviewing this code for awhile and I can't find what's different than my text book. Why won't it work? I want a sum to compute after the user types in two integers. I've even gone as far a counting the characters in each line--everything is the same. Thank you.

    <script type = "text/javascript">
    <!--
    var firstNumber; // first string entered by user
    var secondNumber; // second string entered by user
    var number1; //first number to add
    var number2; //second number to add
    var sum; //sum of number1 and number2

    // read in first number from user as a string
    firstNumber = window.prompt("Enter first integer" );

    // read in secondnumber from user as a string
    secondNumber = window.prompt("Enter second integer" );

    //convert numbers from strings to integers
    number1 = parseInt( firstNumber );
    number2 = parseInt( secondNumber );

    sum = number1 + number2; // add the numbers

    //display the results
    document.writeIn( "<h1>The sum is " + sum + "</h1>");
    // -->
    </script>

    error in this line
    document.writeIn( "<h1>The sum is " + sum + "</h1>");

    it is writeln i.e "L" and not "I"
    writeln means "write line"

    make the change,and it will work perfectly.
