When you delete the contents of a cell with a formula, you delete the
formula, not just the results. To delete the data, you must delete it only
from the cells being referenced by the formula.
Thanks for that but:
I have therefore three cells. A1 has data only, B1 has
the formula but from what you say it seems that I need to
put the result in C1 and hide B1 to protect the formula.
My formula =IF(A1="","",IF(OR(A1="X",A1="Y"),"",A1)) What
change do I need to make to the formula to put the result
in cell C1 and how does the user refresh C1 if he deletes
the data?
