Sorting multiple columns with lookup values

[eltharion]

(Lookup values are when a cell contains "=B4" correct?)

I have three columns: A has names, B has lookup values, C has lookup values as well. I want to be able to sort Column B from largest to smallest. I need to keep the rows together that correspond with values in Column B. And if there's a way to have Column C's values be the tiebreaker if Column B's values are the same that would be great! If not, then they do not have to be in any order. If I try Data->Sort I get a bunch of errors since they're all lookup values. I used a formula a long time ago that sorted this but I've long since forgot it.

I have a simple example as the attachment.

Any help is appreciated!
