Above is what I want it to look like (manually entered)
I need a formula for and event of Evens, Heads and Tails
To count down to the next instance of the event, 0 (Zero) would be if event it is next
(A Blank would be better than a 0 (Zero) if possible.
I have tried formula's with Match but no good
It is really saying the event has not occurred for this many rows.

Thanks Jose', that worked perfect!
Appreciate your help

Copy cross and down.
