Thanks jaco. You just hit the nail on the head. I forgot to remove the [wh]
after the smooth operation (changed a[wh] to a and couldn't work out why it
wasn't working!!!), therefore I was getting array size errors. There were a
few further lines I had to add to do exactly what I wanted but that seems
to have solved my problem. Thanks folks. Now on to the next part of the
code.......

Cheers
