Michael and Burr thanks,

Your post 2728.2 was my original way I wanted to go and it frustrated me for ages.---heaps of files trashed with an expletive!
And I needed to REMEMBER this!

"Then I removed the flat parts to open up a hole"

The rules take up a page,

The "special rules" take up volumes?

STILL browned off.
But thanks anyway.
