Hi All, I have a webpage with a group of radio buttons and a text box. when a radio button is clicked, a value is put into the text box. What I would like to be able to do is have another two radio buttons to set the value for delivery. If 'standard delivery' is checked, then the price doesn't change - however if 'collect at store' is checked, I would like the value in the text box (the price of the goods) to be multiplied by 0.88 if their value is below £100 (this takes off the 12% delivery charge on orders under £100). The page I'm referring to can be found here: http://www.outlook-group.com/outlook_images/gallery/your_image.php?id=23 Any help would be most appreciated! Many Thanks, dai.hop
