problem in ADO find method

reference(my old query):-
friends, i have used vb 6.0 and ms access. i am using ADO type recordset. my requirement is to find match criteria on the basis of two fields: sample code: .Find "Month = " & 1 & " AND FmtFunct = '" & txtFormatId.Text & txtFunctionId.Text & "'" here my search criteria contains one numeric field and another character field which has to be searched simultaneously. it is not accepting.
reply from Macintosh(Junior Member):-

Assuming there is 2 fields in ur table to search field 1 - Month - numeric field 2 - FmtFunct - Text Dim strFmtFunct As String Dim Rs as New ADODB.Recordset strFmtFunct = txtFormatId.Text & txtFunctionId.Text Now use Rs.Open "Select * from TableName", Connection Rs.Find "Month = " & 1 & " AND FmtFunct = '" & strFmtFunct & "'" This will work.....
