Hello Experts,
I've been attempting to create a macro to delete duplicate rows and leave only one (excluding header row) where columns A, C, E, F and H are duplicates. Sometimes column E and F may be empty. I'd like to delete the duplicates only if column J is blank. I've tried the code below but it does not work.

VBA Code:
Sub DeleteDuplicatesIfBlank()
   
    Const dColsList As String = "A,C,E,F,H" ' Duplicate Columns List (2 at least)
    Const bCol As String = "J" ' Blank Column
    Const Delimiter As String = "||" ' Dictionary Delimiter
   
    ' Create a reference to the range ('rg').
    Dim wb As Workbook: Set wb = ActiveWorkbook
    Dim ws As Worksheet: Set ws = wb.Worksheets("Worklist Data")
    Dim rg As Range: Set rg = ws.Range("A1").CurrentRegion
   
    ' Write the Duplicate columns to the Duplicate Columns Array ('dCols').
    Dim dCols() As String: dCols = Split(dColsList, ",")
    Dim dUpper As Long: dUpper = UBound(dCols)
   
    ' Define the Dictionary ('dict').
    Dim dict As Object: Set dict = CreateObject("Scripting.Dictionary")
    dict.CompareMode = vbTextCompare ' ignore case i.e. A=a
   
    ' Declare additional variables.
    Dim drg As Range ' Delete Range
    Dim rrg As Range ' Current Row Range
    Dim n As Long ' Duplicate Column Counter
    Dim cString As String ' Current String (created from the Duplicate Columns)
   
    ' Loop through each row ('rrg') of the range.
    For Each rrg In rg.Rows
        ' Only consider the row if its Blank Column is blank.
        If Len(CStr(rrg.Columns(bCol).Value)) = 0 Then
            ' Concatenate the strings from the Duplicate Columns to 'cString'.
            cString = CStr(rrg.Columns(dCols(0)).Value) ' first
            For n = 1 To dUpper ' remainder
                cString = cString & Delimiter & CStr(rrg.Columns(dCols(n)))
            Next n
            If dict.Exists(cString) Then ' duplicate found
                ' Combine the Current Row Range into the Delete Range.
                If drg Is Nothing Then
                    Set drg = rrg
                Else
                    Set drg = Union(drg, rrg)
                End If
            Else ' not a duplicate, so add it to the Dictionary
                dict(cString) = Empty
            End If
        'Else ' The Blank Column is not blank: do nothing.
        End If
    Next rrg
   
    If drg Is Nothing Then Exit Sub ' no duplicates found
   
    ' Delete the rows containing duplicates. Possible data to the right
    ' of the range will not be affected.
    drg.Delete ' for entire rows use drg.EntireRow.Delete
   
End Sub

Any assistance would be greatly appreciated.
