Hi there,
Code such as the one below copies formulas in the last cells of columns
3 and 10 down to the new rows when inserted. However, I need to allow
the user to overwrite the formula in column 3 with any text value. If
the user overwrites this formula on the last row, and then manually
goes to a new row, then the code below doesn't work (it simply copies
what value is in the above cell).

Is there a way for code search upward in columns 3 and 10 until it
reaches the last cells with formulas, and apply the formulas to the new
cells in columns 3 and 10 on the new row?

Or, is there a way to store the formulas:

=IF(A21<"",B21,"") in column 3
=IF(B21<0,IF(C21<B21,A21&", "&LEFT(C21,2),A21&", "&LEFT(B21,1)),"")
in column 10

behind the worksheet?

'This code carries formulas down from the previous row but does not
'take into consideration if the formula has been overwritten in the
row above.

If Intersect(Target, Me.Range("A:A")) Is Nothing Then Exit Sub
On Error GoTo CleanUp:
With Target
If .Value < "" Then
Application.EnableEvents = False
.Offset(0, 3).FormulaR1C1 = "=RC[-1]=R2C3"
.Offset(0, 10).FormulaR1C1 = "=RC[-1]=R2C10"
End If
End With
CleanUp:
Application.EnableEvents = True

Thanks a lot!
