Ok This attempts to set up the range of where the cursor can return a value and where it should be ignored. The line says Set Preview is where you change the preview cell in between the quotes.
You need to insert this code into the worksheet module. To do so open your workbook, press ALT + F11, on the left side of the new screen you will see VBAProject followed by your workbook name. Double click the sheet below that has the data and then paste the following code in.
Code:
Private Sub Worksheet_SelectionChange(ByVal Target As Range)
Dim Preview As Range, BlankCol As Long, BlankRow As Long
Dim StartRow As Long, StartCol As Long
Set Preview = Range("M1") 'Set the reference you want
'Set other references
StartRow = 2
StartCol = 1
'Auto set the boundaries
BlankCol = Cells(StartRow, StartCol + 1).End(xlToRight).Column + 1
BlankRow = Cells(StartRow, StartCol + 1).End(xlDown).Row + 1
'Ensure you are in the right area
If Target.Column < BlankCol And Target.Column > StartCol Then
If Target.Row < BlankRow And Target.Row > StartRow Then
Preview = Target.Value
End If
End If
End Sub
Let me know if you have any questions.
Thanks
