Going backwards?

I’m trying to make it so in this footer i’m creating you can go back and forth between lyrics. How do I do that? i’m using xml as the source of text. I’ll attach both. Nevermind, definately not a footer anymore, it’s almost 500 Kb, but I still want to know how it’s done.

Here’s the link: http://www.filefactory.com/get/v3/f2.php?f=666a5d

I attached the xml file, the only problem is that this forum doesn’t support .xml as attachments so i made it a .txt

48 people looking on this forum and not a single one has looked in 19 minutes? :run: !!!
