Here's a macro that ALMOST works perfectly:

Sub TryNew()
Dim myCount As Integer
Dim myCell As Range
myCount = 0
For Each myCell In Range("E6", Range("E65536").End(xlUp))
If myCell.Value & myCell(1, -2).Value & myCell(1, -1).Value < myCell(2,
1).Value & myCell(2, -2).Value & myCell(2, -1).Value Then
myCell(1, 13).FormulaR1C1 = "=RC[-14] & "", "" & RC[-13]"
myCount = 0
Else
myCount = myCount + 1
End If
Next myCell
End Sub

Rows C, D, and E are the ones referenced in the above. C contains the Last
name, D contains the First name, and E contains a year value (text). I am
writing out the concatenated Last Name, First Name pair into a vacant cell to
the right of other data.

The idea here is that every time there is a change of ANY OF THE THREE
components, the "Then" result fires. And it does -- ALMOST every time.

The one exception is when only the First Name changes. Then "Then" doesn't
fire.

Example:

SMITH JOHN 1999
SMITH JOHN 1999 "Then fires"
SMYTHE JOHN 1999
SMYTHE JOHN 1999 "Then fires"
SMYTHE JANE 1999
SMYTHE JANE 1999 "Then does NOT fire!"

Any ideas what is going on?
