I am getting the following error when I try to open an ADO Recordset

Run-Time error 3709.
Operation is not allowed on an object referencing a closed or invalid connection.

This doesn't happen every time either. But when I check rsMine.State it is 0 (closed) and it is a valid recordset because it works the first time and it is a read only recordset so I can't change it.

Here is the function that screws up.

Public Function LoadComboBox(rsMine As ADODB.Recordset, cboBox As ComboBox)
   With cboBox
      .Clear
      If rsMine.State = 0 Then rsMine.Open
      While Not rsMine.EOF
         If Not IsNull(rsMine!Name) Then
            .AddItem rsMine!Name
            .ItemData(.NewIndex) = rsMine!ID
         End If
         rsMine.MoveNext
      Wend
   End With
   Set rsMine = Nothing
End Function
