If, then: to run macro

[Sandy]

Hi

Is it possible to have a macro run when a certain condition is met on a
worksheet (or between worksheets).

Example:

If CellA1 on sheet1 <> CellA1 on sheet4 then run the macro "Evaluate"
otherwise do nothing

Thanks

Sandy

Using event code


Private Sub Worksheet_Change(ByVal Target As Range)
Const WS_RANGE As String = "A1" '<== change to suit

On Error GoTo ws_exit
Application.EnableEvents = False

If Not Intersect(Target, Me.Range(WS_RANGE)) Is Nothing Then
With Target
If .Value <> "Worksheets("Shete4").Range("A1").Value Then
' do your stuff
End If
End With
End If

ws_exit:
Application.EnableEvents = True
End Sub

'This is worksheet event code, which means that it needs to be
'placed in the appropriate worksheet code module, not a standard
'code module. To do this, right-click on the sheet tab, select
'the View Code option from the menu, and paste the code in.

It is possible to do this if the contents on the cells are defined by data
entry rather than calculation. The macro is called an Event Macro. For
information see:

You can use the calculate event if the cells are defined by calculations,
but you need to be careful to avoid infinite loops.
