This will give you a little more control over the number of rows that are
inserted:
Sub InsertBlankRows()
'-- Ken Wright, 2003-08-09
Application.ScreenUpdating = False
Dim numRows As Long
Dim r As Long
Dim Rng As Range
Dim lastrw As Long
numRows = InputBox("How many Rows")
lastrw = Cells(Rows.Count, "A").End(xlUp).Row
Set Rng = Range(Cells(1, "A"), Cells(lastrw, "A"))
For r = Rng.Rows.Count To 1 Step -3
Rng.Rows(r + 1).Resize(numRows).EntireRow.Insert
Next r
Application.ScreenUpdating = True
End Sub
