thanks for assisting. I now need to "move" a group of "boxes" as a whole unit further up the page so as not to have a gap in middle of page, without moving and trying to align every single one of them next to each other manually. I've tried cut and paste but that doesn't work. there must be a way, can you or any one else assist?
What kind of "boxes"? Text fields? Static contents?
