Hi
This sample code will insert a blank row every time value entered in column
B is different from value one row above.
Right-click on your worksheet's tab, choose View code and paste the
following exemple :

Private Sub Worksheet_Change(ByVal Target As Range)
If Target.Column < 2 Or Target.Row = 1 Then Exit Sub
If Target.Offset(-1, 0).Value < Target.Value Then
Target.EntireRow.Insert
End If
End Sub

I am very new to VBA so any help would much appreciated.

I would like to know how to write a macro that inserts an entire row
of cells everytime the the data in cell b is different from the cell
above it. It would need to be a continuous process until there was no
more data.

eg.

A B

10 40
12 40 < Insert a row between the 40 and 60
17 60
22 60 < Insert a row between the 60 and 70
24 70
29 70

Dim i As Integer
i = 2
While Range("C" & i) < ""
Do
If Range("C" & i) < Range("C" & i + 1) Then
Rows(i & ":" & i + 1).Insert Shift:=xlDown
i = i + 1
End If
i = i + 1
Loop
Wend

The above was some code that I came up with but I am pulling my hair
out trying to make it work

Thanks for any help
