The bad news is that you're looping through the cells in that column. And if
there are duplicates, you're processing that data more than once.

Instead of modifying the code you have, you may want to look he

Ron de Bruin's EasyFilter addin:
http://www.rondebruin.nl/easyfilter.htm

Code from Debra Dalgleish's site:
http://www.contextures.com/excelfiles.html

Create New Sheets from Filtered List -- uses an Advanced Filter to create
separate sheet of orders for each sales rep visible in a filtered list; macro
automates the filter. AdvFilterRepFiltered.xls 35 kb

Update Sheets from Master -- uses an Advanced Filter to send data from
Master sheet to individual worksheets -- replaces old data with current.
AdvFilterCity.xls 55 kb

If you're new to macros, you may want to read David McRitchie's intro at:

I need some help modifying this macro. I found this in a post by
Bernie Deitrick:

Sub ExportDatabaseToSeparateFiles()
'Export is based on the value in the desired column
Dim myCell As Range
Dim mySht As Worksheet
Dim myName As String
Dim myArea As Range
Dim myShtName As String
Dim KeyCol As Integer

myShtName = ActiveSheet.Name
KeyCol = InputBox("What column # within database to use as key?")

Set myArea = ActiveCell.CurrentRegion.Columns(KeyCol).Offset(0,
0).Cells

Set myArea = myArea.Resize(myArea.Rows.Count - 1, 1)

For Each myCell In myArea
On Error GoTo NoSheet
myName = Worksheets(myCell.Value).Name
GoTo SheetExists:
NoSheet:
Set mySht = Worksheets.Add(befo=Worksheets(1))
mySht.Name = myCell.Value
With myCell.CurrentRegion
.AutoFilter Field:=KeyCol, Criteria1:=myCell.Value
.SpecialCells(xlCellTypeVisible).Copy _
mySht.Range("A1")
mySht.Cells.EntireColumn.AutoFit
.AutoFilter
End With
Resume
SheetExists:
Next myCell

'Optional section to export the sheets to separate files
'For Each mySht In ActiveWorkbook.Worksheets
'If mySht.Name = myShtName Then
'Exit Sub
'Else
'mySht.Move
'ActiveWorkbook.SaveAs "Workbook " & ActiveSheet.Name & ".xls"
'ActiveWorkbook.Close
'End If
'Next mySht

End Sub

And it does almost what I want it to do. Unfortunately I have 2
worksheets and when this divides the data out it overwrites everything
from the first worksheet. I have tried to find some Append macros to
combine with this but I am not very proficient in visual basic.
Anyone out there know have some ideas?

Thank you for the help,

Dow.
