Hey

Could anyone guide me in the right direction on this:

I want something like: Amazon.com Coupon Codes - all coupons, discounts and promotion codes for amazon.com

The part, 'Did this coupon work for you'

I want that, so when yes or no is clicked, the new percentage is brought back.

Someone said I need to do:
Onclick on worked button, send url to php script via ajax that adds +1 to the database and then use mysql and stuff on the php script to return the value of percentage.

However, I'm kinda new to this stuff so .. Can anyone do the javascript bit and I'll do the PHP page?

Thanks, help much appreicated.
