Change row colour each time cell value changes

[coops_46]

I have reference numbers in Cell A2:A250
Each time one of these number's changes, can the whole row change colour?
When the cell value changes again, I need the colour to change again. It doesn't have to be a different colour each time, just alternate between no fill and fill with red, for example.

Thanks in advance

Give this event code a try...

[table="width: 500"]
[tr]
	[td]Private Sub Worksheet_Change(ByVal Target As Range)
  If Target.Count = 1 Then
    If Not Intersect(Target, Range("A2:A250")) Is Nothing Then
      Target.EntireRow.Interior.ColorIndex = xlColorIndexNone + 3 - Target.EntireRow.Interior.ColorIndex
    End If
  End If
End Sub[/td]
[/tr]
[/table]

HOW TO INSTALL Event Code
------------------------------------
If you are new to event code procedures, they are easy to install. To install it, right-click the name tab at the bottom of the worksheet that is to have the functionality to be provided by the event code and select "View Code" from the popup menu that appears. This will open up the code window for that worksheet. Copy/Paste the event code into that code window. That's it... the code will now operate automatically when its particular event procedure is raised by an action you take on the worksheet itself. Note... if you are using XL2007 or above, make sure you save your file as an "Excel Macro-Enabled Workbook (*.xlsm) and answer the "do you want to enable macros" question as "yes" or "OK" (depending on the button label for your version of Excel) the next time you open your workbook.
