    Thank you for your replpy.

    Prior to this, when I run my coding and your sample workbook in Microsoft Office XP and Microsoft Windows XP, it can run smoothly.

    When I run my coding and your sample workbook in my home PC (in Microsoft Office 98 and Microsoft Windows 98 platform), the error occur.



    Thanks again for your reply.

    I have downloaded your sample coding for my problem. I have put your macro coding to run, sometimes it could run smoothly and SOMETIMES the button could not function at all and the error message is "Run Time Error '457' This key is already associated with an element of this collection." The error yellow box has highlighted on on the line "NoDupes.Add Cell.Value, CStr(Cell.Value)".

    This happen to my coding as well. Sometimes the user form which hold my combobox COULD BE INITIALIZE SMOOTHLY, and sometimes IT COULD NOT.
    The SAME error message pop up by placing the same line in YELLOW BOX.

    Here is my coding:-

    Private Sub UserForm_Initialize()

    Dim rngTable As Range
    Dim rngCell As Range
    Dim NoDupes As New Collection
    Dim intI As Integer
    Dim intJ As Integer
    Dim Swap1, Swap2, Item
    Dim AllSheets As Worksheet

    For Each AllSheets In ActiveWorkbook.Worksheets
    Set rngTable = AllSheets.Range("A4:A" & AllSheets.Cells(Rows.Count, "A").End(xlUp).Row)

    On Error Resume Next

    For Each rngCell In rngTable
    If rngCell.Value <> "TOTALS" Then

    NoDupes.Add rngCell.Value, CStr(rngCell.Value)

    End If

    Next rngCell

    On Error GoTo 0

    Next AllSheets

    'Sort the collection
    For intI = 1 To NoDupes.Count - 1
    For intJ = intI + 1 To NoDupes.Count
    If NoDupes(intI) &gt; NoDupes(intJ) Then
    Swap1 = NoDupes(intI)
    Swap2 = NoDupes(intJ)
    NoDupes.Add Swap1, before:=intJ
    NoDupes.Add Swap2, before:=intI
    NoDupes.Remove intI + 1
    NoDupes.Remove intJ + 1
    End If

    Next intJ

    Next intI

    'Add the sorted, non-duplicated items to a comboBox
    For Each Item In NoDupes

    frmTotalInvoiceServiceID.cboGenerateSelectServiceID.AddItem Item

    Next Item

    End Sub

    Really hope that you could help me on this. Thank you.



    thank you for your reply but unfortunately, the sample coding from J-Walk doesn't seem to work in my case.

    I got this error message saying that Run Time Error '457' which said that the NoDupes key is already associated with an element of this collection.

    Do you know how to solve this problem?

    Thank you.

    I have 3 worksheets in my Activeworkbook. Worksheet 1 has number 101,102,1000,1001,1002 in it in vertical format in column A. Worksheet 2 has number 101,102,1000,1001,1002,1003,1004 in it in vertical format in column A. Worksheet 3 has 101,102,1000,1001,1002,1003 in it in vertical form also in Column A. I have done the initialization VBA coding to initialize those numbers into my combobox, instead of loading those UNIQUE numbers into my combobox, it load all the numbers into my combobox and as a result I have duplicate items in my commbox (for example, number 101 appear 3 times instead of appearing only once in my combobox). Here is my VBA coding:-

    Private Sub UserForm_Initialize()

    Dim intIndex As Integer
    Dim shtThisSheet As Worksheet
    Dim strServiceID As String
    Dim rngData As Range
    Dim rngCell As Range

    'set range table
    For intIndex = 1 To 3
    Set shtThisSheet = ActiveWorkbook.Worksheets(intIndex)

    'currentregion to find range with data
    Set rngData = shtThisSheet.Range("A3").CurrentRegion
    Set rngData = rngData.Offset(Rowoffset:=2) _
    .Resize(rowsize:=rngData.Rows.Count - 3, ColumnSize:=rngData.Columns.Count - 6)

    'assign column heading strServiceID variable
    strServiceID = "ServiceID"

    'sort ServiceID data, then add only unique ServiceIDs to combobox
    rngData.Sort key1:=strServiceID, header:=xlYes
    For Each rngCell In rngData.Cells
    If rngCell.Value <> strServiceID Then
    cboAddExistingDataSelectServiceID.AddItem rngCell.Value
    End If

    Next rngCell

    Next intIndex

    End Sub

    All help is very much appreciated. Thank you.
