Um...don't they have a tutorial for this? It's pretty straight forward. There are numbers on the springjumps, 0 is for the home page, 1 is the next page, 2 is the next, and so on. You tap on them to jump to the according page.
If you can't see the numbers...you disable your theme and relocate the springjumps to where the theme requires and then enable the theme.
If you still have problems with it then I suggest you don't use that theme lol. Sorry to be so straightfoward but yeah, that's what it is.
