[renormalised (Carl)]

Hi Michael and welcome to IIS

I'd give you some advice but right now my head isn't in the right place because I spent all last night and the morning chasing comets, and I'm just about ready to shutdown for at least....long enough to recover!!!

I'm sure someone will pipe up and give you plenty of good advice. There are very many knowledgeable people in this forum who are more than willing to help out
