Thanks Jim - I've got it. As soon as I read your reply about grayed out because only 1 data set I realised that I was trying to do this in the new project with only 1 entry instead of in my project. A good sleep and a fresh head, along with your reply solved it perfectly. I am once again a happy little? camper.
Now I'm off to back up this version to the laptop.
Regards
Merle
