Access 2000 File Browser Code Does not Work in Access 2003

I program a script to display a window for the user to browse to a file to import. It only works in Access 2000, but not in Access 2003. CommonDialog.MSComDlg.CommonDialog.1  Error is Object does not support property or method.

Private Sub btn_Browse_Click()
On Error GoTo ErrorHandler

    ComDialog.CancelError = True
    ComDialog.DialogTitle = "Select File Name"
    ComDialog.Filter = "XLS Files (*.XLS)|*.xls"
    ComDialog.DefaultExt = "csv"
    ComDialog.ShowOpen
    Form_frm_ImportFile.FileName.Value = ComDialog.FileName
       
Exit_btn_Browse_Click:
    Exit Sub
   
ErrorHandler:
    If Err.Number = 32755 Then Exit Sub
    MsgBox Err.Description, vbOKOnly
    Resume Exit_btn_Browse_Click
End Sub
