Thankyou for your help, but I'm already at this stage
Pigs might fly
I thought I'd almost cracked it with your help, but no. I can add up hours with your method, but adding up hours that have already been part of a former calculation (ie Take off & Land times) - it won't work for me. Could you perhaps e mail me, attaching a blank part of your log, complete with formulas?
cheers.
