I want to use Ron de Bruin's
http://www.rondebruin.nl/delete.htm
AutoFilter code to delete a lot of rows.
The criteria for rows to be deleted is:
=OR(NOT(ISNUMBER(B9));AND(ISNUMBER(B9);ISTEXT(C9)) ;LEFT(D9;4)="Side")
from row 9 to row 30.000.

Any help on how to put this formula into Ron's below code:

Regards
Hans Knudsen


Sub Delete_with_Autofilter()
Dim DeleteValue As String
Dim rng As Range
Dim calcmode As Long

With Application
calcmode = .Calculation
.Calculation = xlCalculationManual
.ScreenUpdating = False
End With

'Fill in the value that you want to delete
'Tip: use DeleteValue = "<ron" to delete rows without ron
DeleteValue = "ron"

'Sheet with the data, you can also use Sheets("MySheet")
With ActiveSheet

'Firstly, remove the AutoFilter
.AutoFilterMode = False

'Apply the filter
.Range("A1:A" & .Rows.Count).AutoFilter Field:=1,
Criteria1:=DeleteValue

With .AutoFilter.Range
On Error Resume Next
Set rng = .Offset(1, 0).Resize(.Rows.Count - 1, 1) _
.SpecialCells(xlCellTypeVisible)
On Error GoTo 0
If Not rng Is Nothing Then rng.EntireRow.Delete
End With

'Remove the AutoFilter
.AutoFilterMode = False
End With

With Application
.ScreenUpdating = True
.Calculation = calcmode
End With

End Sub
