Hello Friends,

I want to tell you about a strange error which's appearing every once in a while in my computer: the file contains information about enterprise employees. It contains many formulae but it works right. However, from time to time the cells begin to show #N/A errors that cannot being eliminated, but only when I replace the data manually.

I've generated a new document from scratch, as well, but the problem goes on. Even in other PCs (at home).

What this could be?

thanks in advance,

Harold
