Fed up

God i'm bored. Each quarter I have to update a bunch of graphs for our quarterly class of business meetings. That wouldn't be a problem as they're not overly complicated, however the guy that designed the damn spreadsheets has made it virtually impossible to do. There must be 20 different sources of data feeding these things, each having to be updated, links remapped, pivots refreshed, years added... yawn, yawn, yawn. And the people this is for have the cheek to expect it to be correct. Good luck...
