Hi Brian,
Thanks for your help and patiens. I think I’m finally getting the hang.
Could not have done it without your scripts, documentation and answering my stupid questions.
Just one more, if ok with you.
How did you work out what to do with the [t=i(numPoins-1)] and [R2 = UserEnteredValue – R1]?
Without me following your Scripts, I would never have worked that out.
