Thank you for that. For a start your expression is way better that the over complicated one I was using so its already quicker. And I definitely have less white space (I still have some but I think I'm just going to have to let that go)

I thought that it might be the spaces between the tables so I pulled all the tables a lot closed together. I think it helped a little bit.

I don't have any page breaks or rectangles. But its better than it was and faster so thank you:-)
