No that's not it Fly.
If you make a card birthday, Christmas etc it can be folded so that all 4 sides have something on.
1 is the front, 2&3 is the middle, 4 is the back.
Once printed it's just a case of folding the paper twice to make the card up.
The numbers are generally situated on the left bottom corner of the card.
I can move between each page to add/ alter what I want just by clicking on the numbers.
It has been working and I printed one off yesterday, but decided to alter the border in the middle - hey ho no numbers, which means I can't get past the front page of the card!
