Marcus,

Here's my attempt at an explanation.

The timer functions only operate when your pronto is on selected pages. You can select any pages you want it to operate on but, but default, it doesn't operate on any of them. To select a page for the timers to operate on, go to the page properties of that page and follow Schmutzli's instructions. By adding the eval command to a page script, you are effectively saying "when on this page, run the timer script".
