Sheet Calculation slow

[nika]

Hi Daniel
Thanks for your reply

and Thanks for the formula. It's an improvement on what I had.
I do a lot of sorting on my data but not F & D as the main sortin
columns, therefore, they are muddled up constantly. Happy to say I a
reasonably happy now with the speed and I suppose this problem ha
helped me learn a bit more about excel.

Thanks agai
