Thanks Rick for your help. It worked very well.

I mistyped Delete instead of ).EntireRow.Delete (see below)....

Just to supplement your posting, here is a subroutine that stops at the
last filled cell in the column (whether internal empty cells exist or
not)...

Sub DeleteRows()
Const C = 2 'Column
Const StartRow = 2 'Starting row
Const SearchData = "CCNU"
Dim R As Long
For R = Me.Cells(Rows.Count, C).End(xlUp).Row To StartRow Step -1
If InStr(Me.Cells(R, C), SearchData) = 1 Then Cells(R, C).Delete

The above line should be this instead...

If InStr(Me.Cells(R, C), SearchData) = 1 Then Cells(R, C).EntireRow.Delete

Next
End Sub

Orquidea,

You can do it a non-macro way, using Autofilter, Custom, CCNU*. Then
select the filtered rows and delete them, then remove the Autofilter.

This macro will do it. It stops at the first empty cell it sees in the
column.

Sub DeleteRows()
Const Coll = 2 ' column
Const SearchData = "CCNU"
Const StartRow = 2 ' starting row
Dim Roww As Long
Roww = StartRow
Do
If Left(Cells(Roww, Coll), Len(SearchData)) = SearchData Then
Cells(Roww, Coll).EntireRow.Delete
Else
Roww = Roww + 1
End If
Loop While Cells(Roww, Coll) < ""
End Sub
