I'm trying to setup that mirror each other at all times. I am currently
handling "Worksheet_Change()" in my sheets, so any time one
sheet gets modified, I am trying to copy the contents of one sheet
to the other.

The shortened code looks as follows:

'
' Sheet 1
'
Private Sub Worksheet_Change(ByVal Target As Range)
changedCell = Target(1).Address(0, 0)
Sheet2.Range(changedCell).Value = Sheet1.Range(changedCell).Value
End Sub

'
' Sheet 2
'
'Private Sub Worksheet_Change(ByVal Target As Range)
changedCell = Target(1).Address(0, 0)
Sheet1.Range(changedCell).Value = Sheet2.Range(changedCell).Value
End Sub

This code generally works when a user changes one cell at a time. However,
(for example) if a user selects a big block of cells on Sheet1 and presses
the DELETE key, that block of cells will actually delete on Sheet1, but only
one (or two or so) cells will delete from Sheet2.

How can I modify the subroutines above to handle cases when a block of
data is highlighted in one sheet, then tell the second sheet to delete all
those
cells as well??

Thank you!!!
