Hello everyone

This error is kinda weird cose sometimes it works and other times don't.
I'm doing some calculations in a file that goes to "read" to seven other files. Mostly Vlookup and count. Very simple. But i'm must be doing something wrong because it doesn't show me any values but errors.
I believe it's important to say that i'm working through a vpn of my company.

Tks for all your help
Best regards
Pedro
