I hope this is the right place to put this..

So Ive made a template in photoshop, figured out how to get the text on the body and linked all of the pages. But my problem now is that if I type to much text to fit on the body there is no scroller or anything it just doesnt show up.. How can I fix this?

What I mean is If I type to much text to appear in the body section and it goes off the template size, it just dissapears.. Can I make a scroller or something?
