Hi Gordon,
thanks for your quick reply, explaining their bizareness. I can't quite get my head around the weirdness, but now I will be able to leave it alone,, and not think I have to go back, chasing it up - thank you.
I don't know how any of them, from employees and contractors to ministers - involved in all this - sleep at night, I really don't.
Thanks for your continuing help and support. It is much appreciated.
