    Need a little help with a discount code

    Hey everyone,

    I'm totally new to this and learning as I go - so please bare with me!

    I need to add a discount code to my website and I can't seem to get it right.
    Using the code "JoeCain" should award the customer a $25 gift certificate.
    I tried my best to write the code, but my total amounts to $25 and not the price minus $25.

    Here's what I have..(ignore the 'frenchfry' code, that one was written by the man who helped with my site)

    switch(discount) {
    case 'frenchfry':
    discount_amount = 0.10
    price = price - (price*discount_amount)
    discount_applied = ' <i>(Applied 10% Off)</i>'
    case 'JoeCain':
    discount_amount = 25
    price = price - (price-discount_amount)
    discount_applied = ' <i>(Applied $25 Off)</i>'

    $('#price').html('Price: $'+price+'.00' + discount_applied )

    This would be javascript, not java (java cannot switch on String datatypes).
    Moving from java to javascript forum.
    PHP Code:
    header('HTTP/1.1 420 Enhance Your Calm'); 
    Been gone for a few months, and haven't programmed in that long of a time. Meh, I'll wing it ;)

    price = price - (price-discount_amount)

    price = price-discount_amount;

    Or, more succinctly:
    price -= discount_amount;

    By the same token, this code:
    discount_amount = 0.10
    price = price - (price*discount_amount)

    Could be written:
    discount_amount = 0.10;
    price -= (price*discount_amount);

    Or, even simpler,
    discounted_rate = 0.90;
    price *= discounted_rate;

    Please be sure to put a semicolon at the end of every JavaScript statement.

    No, it's not required. But there are a few cases where what YOU think is the end of the statement turns out not to be where JS thinks it is. Play it safe.
