Aladin that is exactly it however, when trying to add another column (to add the next year, e.g. 2010) it isn't automatically added to the formula. Is there anyway to correct that? It needs to be able to be updated every year.
Thanks for your help.
If you were to put the calculation on the left side like I did in this example then it's a whole lot easier (KISS).

This array formula** entered in B2 and copied down:
=LOOKUP(100,FREQUENCY(IF(C2:Z2="Not Burnt",COLUMN(C2:Z2)),IF(C2:Z2<>"",IF(C2:Z2<>"Not Burnt",COLUMN(C2:Z2)))))
** array formulas need to be entered using the key
combination of CTRL,SHIFT,ENTER (not just ENTER).
Hold down both the CTRL key and the SHIFT key
then hit ENTER.
How many years of records do you anticipate in needing?
In the formula I use the range from column C to column Z which will accommodate 24 years worth of records. If you think you will not need that many columns of data then just reduce the last column from Z to a lesser column like say, column R?
