All I want to do is display the Record Set on screen (only if records are found) in table format or perhaps print it; which ever is easier.

However; I continually get one of these errors... "Type Mismatch" OR "Can't Assign to Array"

I have found a couple of previous questions that are good examples, however neither solution resolves my problem...

http://search.experts-exchange.com/Microsoft/Development/MS_Access/Access_Coding-Macros/Q_22864730.html?sfQueryTermInfo=1+arrai+assign+can%27t

My code is attached.
Function FindDuplicates()
   Dim DB As Database
   Dim TheRecordSet As Recordset
   Dim RecordSetArray() As Variant     '<----- Related to error
   Dim NumOfRecords, RSRows, RSCols As Long
   Dim ModuleName, ErrorText, SQLQuery1 As String
   
   ' Initialize Error Routine
   On Error GoTo ThreeStoogages
   ModuleName = "FindDuplicates()" & Chr(10) & Chr(13)
   ErrorText = ModuleName & Chr(13) & Chr(10) & "Initialize All Variables"
   
   Set DB = CurrentDb()
   NumOfRecords = 0
   
   MsgBox "Begin VB Module Process: " & ModuleName & Chr(13) & Chr(10) & "Is used to identify duplicate records", vbInformation, "VB Module Execution"
   
   ' The SELECT Query
   SQLQuery1 = "SELECT blah, blah, blah..."
   ' MsgBox SQLQuery1, vbInformation, "SQLQuery1 Variable Contents"
   
   ' Create the RecordSet
   ErrorText = ModuleName & Chr(13) & Chr(10) & "Initialize Record Set"
   Set TheRecordSet = DB.OpenRecordset(SQLQuery1, dbOpenSnapshot)
   TheRecordSet.MoveLast
   TheRecordSet.MoveFirst
   NumOfRecords = TheRecordSet.RecordCount
   
   ' Store the Record Set into an Array
   ErrorText = ModuleName & Chr(13) & Chr(10) & "Store the Record Set in an Array"
   Set RecordSetArray = TheRecordSet.GetRows(NumOfRecords)     '<----- Error occurs here
   
   ' Get the Array Column and Row Count
   ErrorText = ModuleName & Chr(13) & Chr(10) & "Get the Column and Row counts in the Array"
   RSCols = UBound(RecordSetArray, 1) 'Returns the Number of Columns in the Record Set - I have 9 columns
   RSRows = UBound(RecordSetArray, 2) 'Returns the Number of Rows in the Record Set - I have 120 records
   
   ' For the Error Routine
   ErrorText = ModuleName & Chr(13) & Chr(10) & "Check for empty Record Set"
   If TheRecordSet.BOF And TheRecordSet.EOF Then
      MsgBox ModuleName & Chr(13) & "No duplicate records found.", vbInformation, "Successful VB Module Execution"
      Exit Function
   Else
      ' Display the Record Set on screen
      ErrorText = ModuleName & Chr(13) & Chr(10) & "Display Record Set"
      MsgBox ModuleName & Chr(13) & "Duplicate records found.", vbInformation, "Successful VB Module Execution"
      
      ' Write any display code here as needed
      
   End If
   
   MsgBox ModuleName & "Found " & NumOfRecords & " Duplicate Records", vbInformation, "Successful VB Module Execution"
   Exit Function
   
' Error Routine
ThreeStoogages: MsgBox "Error Type: " & Error() & Chr(13) & Chr(10) & ErrorText, vbInformation, "Un-Successful VB Module Execution"
 
End Function

Try declaring your array differently:

Dim RecordSetArray As Variant     '<----- Related to error

Note also you may need to remove teh Set call:

RecordSetArray = TheRecordSet.GetRows(NumOfRecords)
0

LSMConsulting,

Thanks, I use this declaration... Dim RecordSetArray() As Variant ...and removed the word SET per your sugestion and it worked! That explains why I coulsd not figure it out, it wasy to easy.

Now all I need to do is display the array in a table or grid, any suggestions (point me in the right direction)?
