I hope I may present the following problem. I have created a simple page with two buttons for readers to order a free book. They can choose a book for iPad or laptop/computer by pressing one button. I would like to connect a counter to those buttons that registers how often one of the two books is downloaded. I guess I'll have to connect an extra script to each button, but unfortunately, I don't know how to make that script with the counter.
Would be very happy with help.
