Description

I need guidance for the pages down below. There is a sheet that contains the following: Vesprs, Epg, etc... I have done some by myself on a operate sheet but i want to see if i'm correct because i looked a lot of it online. I need someone to help me understand these problems, because some i couldn't directly find correlations to online sources. Thank you.
