I'll try my best to explain this:

First formula needed in Sheet1 cell A2: If Sheet1 cell B2 = Sheet2 cell B2 then return a 1. If not then return a 0.

Second formula needed in Sheet3 cell A1: Copy all the rows of Sheet1 that have a 1 in A:A. Preferably with no empty rows in Sheet3, just the data list.

This is driving me nuts, so any help is really appreciated.

Cheers.
