Thanks for the replies, I'll go to war on the
little varmints tomorrow.

BTW, this is a great NG I'm glad I found it,
I'll sit on the side and read all the posts and
maybe learn a bit more like that.
I may even know the answers to some of your
questions.

Probably pop in from time to time with the
odd question when I get stuck.

Thanks again.

Wally
