Do the cells that don't change contain text instead of numbers? Try
=ISTEXT(A1) with the A1 being changed to the appropriate cell reference.

Hello Excel experts:

I have one doubt in this following sheet:

1997
EU (27 countries) 100
EU (25 countries) 104,9
EU (15 countries) 115,5
Euro area 115,9
Euro area (15 countries) 0
Euro area (13 countries) 114,4
Euro area (12 countries) 114,7
Belgium 125,9
Bulgaria 26,5
Czech Republic 73,1
Denmark 133,5
Germany 124,6
Estonia 41,9
Ireland 115,1

If I change point for comma format in cells just change in several ones
but
not in all of them could you tell me please?

thanks
