Hi Johnny
try this macro

Sub InsertRow()
Dim c, d, nr As Long
nr = Range("A1").CurrentRegion.Rows.Count

For i = nr To 2 Step -1
Cells(i, 1).Select
c = Cells(i, 1).Value: d = Cells(i - 1, 1).Value
If IsNumeric(c) And IsNumeric(d) And _
Cells(i, 1) < Cells(i - 1, 1) Then
Selection.EntireRow.Insert
End If
Next i
End Sub


Regards
Peter

hi
formulas return values. they can not perform actions like insert row.
there is a keyboards shortcut for it.
ctrl+ plus sign - insert a cell
crtl+ minus sign - removes a cell
high light row ctrl+ plus sign - adds a row
high light row ctrl+ minus sign - removes a row
