MancBoy,
the problem sometimes with these forums is that things do not come out properly.
What you have explained makes perfect sense. When I read it before it was binned; it sounded like it was a multiple a/c scenario and a complicated one to boot.
As well as being mis-construed, you can't always guarantee that the proper recipient will be reading the thread.
At least you had the balls to bin it, then explain why, which is more than some people ever do!!
