Hmm.
Hey, Mathieu. Many thanks for the reply. However, I currently AM using a
form. What I'm trying to get away from, is the two step process:
1. pick your option
2. click submit
I'm trying to get a one-step process, where the user can click on a link,
and that calls the function.
JavaScript won't work, because it's client side, and can't be used to call
a server-side php function (unless you tell me some neat trick I don't
know about yet). See my struggle now?
