I need a lot of help here. I am trying to add another value, a simple number, to my entries file, but the main problem is that I will need to edit this value later. (I will need to add 1 to it). I hope to be able to use this value as a sort of rating kind of thing, so users can be able to click a link to mark a certain guestbook entry as "Excellent," for example. So, in short, a user clicks the "excellent" link, and when they reload, this value, which is counting how many excellents there are, will increase one number. I know where to add the "excellent" link and how to add this value to each entry, but I don't know how to edit this value, when the user clicks "excellent." I hope you understand what I mean. Thanks so much for the help, in advance!
