That needs VBA.

Private Sub Worksheet_Change(ByVal Target As Range)

On Error GoTo ws_exit:
Application.EnableEvents = False
If Not Intersect(Target, Me.Range("A1:A10")) Is Nothing Then
With Target
If IsNumeric(.Value) Then
.Resize(.Value).EntireRow.Insert
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.

Need formula that will allow a number e.g. 5 to be placed in a cell, which
t\will then insert 5 rows. Thanks
