    Percentage Function - Please help

    Hello there.

    I have the following code and i would like to show in the results a percentage and a VAT ammount.

    Here is my code:

    <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">
    <head>
    <title>Online Sales Order For BT1102</title>
    <script type = "text/javascript">
    <!--
    var name,
    code,
    strNumber1,
    strNumber2,
    intNumber1,
    intNumber2,
    intMinus,
    intSum;
    name = window.prompt ( "Enter The Name", "0" );
    code = window.prompt ( "Enter The Code", "0" );
    strNumber1 = window.prompt ( "Enter Retal Price", "0" );
    strNumber2 = window.prompt ( "Enter Promotional Price", "0" );

    intNumber1 = parseInt ( strNumber1 );
    intNumber2 = parseInt ( strNumber2 );

    intSum = intNumber1 + intNumber2;
    intMinus = intNumber1 - intNumber2;

    document.writeln ("<h1> Online Sales Order Request Form</h1>");
    document.writeln ("<h2> Product Description: " + name + "</h2>");
    document.writeln ("<h2> Product Code: " + code + "</h2>");
    document.writeln ("<h2> Value Of Order at RPR: " + intNumber1 + "</h1>" );
    document.writeln ("<h2> Value Of Order at PP: " + intNumber2 + "</h1>" );
    document.writeln ("<h2> Saving made by PP: $" + intMinus + "</h1>" );
    document.writeln ("<h2> Saving made by PP: $" + intperc + "</h1>" );
    // -->
    </script>

    </head>
    <body>
    <p>Click Refresh </p>
    </body>
    </html>

    The percentage must be the ammount of intNumber1 minus intNumber2.
    The VAT of 17.5% must be inserted on intNumber2.

    How can i show these two function under document.writeln?

    Thanks!!!

    Question Questions about calculations ...

    The percentage must be the ammount of intNumber1 minus intNumber2.
    The VAT of 17.5% must be inserted on intNumber2.
    I'm not sure I fully understand why you are using integers for % calcualtions,
    but try:
    // sum is retail price
    // PLUS // [not sure why ???]
    // (promotional price multiplied by VAT)
    intSum = intNumber1 + (intNumber2 * 0.175);
    // why PLUS above ???
    // should it be???: intSum = intNumber2 + (intNumber2 * 0.175);

    // intMinus is retail price MINUS promotional price alone
    intMinus = intNumber1 - intNumber2;
    // not sure why VAT is not utilize here also for the calculation

    // percentage saved
    intperc = intMinus / intSum;
    Your calculations don't make sense to me, but it will give what you write.
    I've added some [questions] inside the brackets.

    Thank you very much.
    This works perfectly for me now!!!
    Im very grateful THANKS again.
    I know some of the functions dont make sence because i forgot to remove some testing i was doing.
    The problem is now fixed and works perfectly as it should.
    Ive been working for this assignment for 2 days now so i kind of lost my sences as i can see now from my post.
    Thanks again.

    You're most welcome.

    I would suggest for future projects that you comment more
    so that the english (?) makes as much sense as the code.
    Makes it a little easier to spot problems when things go awry.
