Hey all,

I have a excel worksheet that keeps track of money changes, so I want to keep track of total amount of money change in one cell, is there any way to make it so that whenever the cell changes, the old data is recorded in a sheet called 'Raw Data'? I want to do this for two other cells also.
The cells are located on B4,C4, and D4. In the cells are formulas, not manually entered data, so in 'Raw Data', I want it to record the cells which are located in 'Main' in the following fashion:

Time and date (A1)-------B4 Changes (B1)-------Time and date (C1)-------C4 Changes (D1)-------Time and date (E1)-------D4 Changes (F1)
1:08 5/08/13 (A2)-------$504 (B2)

Thanks!
