To answer Melone's query,
If the range of cells is say B5:B18, to find the address of the cell with the max use the following expression:
=CELL("address",OFFSET(B4,MATCH(MAX(B5:B18),B5:B18,0),0))
This will return the first instance of the maximum value; I don't know how you could possibly return more than one address (for 2 or more of the same max values) unless you use a VBA approach.
