PROBLEM: cannot accurately determine Last Row / Last Column on worksheet
using either of the two code sets below

CAUSE: worksheet is a "shell" into which new files are pasted each month.
They vary in both # of Rows and Columns each month. I delete rows and columns
of prior month as a first step in macro. (I cannot close and re-open the
worksheet - doesn't work either!)

WHAT MAKES ME CRAZY! The resulting #s will be prior month's total rows and
columns IF the prior month's file was larger. I've used the code sets below
but neither accurately determines the last Row / Last Column. I must be
missing something really basic (every pun intended!)
All advice will be gratefully appreciated.'




CODE SETS:
'
FinalRow = ActiveCell.SpecialCells(xlCellTypeLastCell).Row
FinalColumn = ActiveCell.SpecialCells(xlCellTypeLastCell).Column
'
'
FinalRow = ActiveSheet.Cells.Find(What:="*", _
SearchDirection:=xlPrevious, _
SearchOrder:=xlRows).Row
'
FinalColumn = ActiveSheet.Cells.Find(What:="*", _
SearchDirection:=xlPrevious, _
SearchOrder:=xlByColumns).Column
'
