Use the Change event if the user will cause the cell to change by editing
it. You would have to construct your code to operate the way you want.
the event is triggered - then your code in the event determines when to act
and when not to act.

Good morning, How could I say to excel that when a cell changes (lets say
a2)
execute something,
something like:
if cells(2,1)<"" then ...bla bla bla

but this works just with cells with no values in them

I want that wherever value is in the cell, when user changes it, execute
the
proceedure.
