Hi -
On my app I need to validate it a certain record exists, before trying to insert a new one. The the existence is determined by a rst.findferst on the rst (a query), that combines two columns.

my code is:

    Dim tblSelecaoDetail_r As DAO.Recordset
    Dim qryMMRfilterNew_rst As DAO.Recordset
    Dim tblSelecaoDetail_rst As DAO.Recordset
    Dim qrySelecaoExistencias_rst As DAO.Recordset
    Dim strLocateSelected As String
    Dim lngNumRecords As Long
    Dim strX As String
    Set BddPlus = CurrentDb
    Set qryMMRfilterNew_rst = BddPlus.OpenRecordset("qryMMRfilterNew", dbOpenDynaset)
    Set tblSelecaoDetail_rst = BddPlus.OpenRecordset("tblSelecaoDetail", dbOpenDynaset)
    Set qrySelecaoExistencias_rst = BddPlus.OpenRecordset("qrySelecaoExistencias", dbOpenDynaset)


   Do While Not qryMMRfilterNew_rst.EOF
        ' acrescentar os registos seleccionados de qryMMRfilterNew à selecção escolhida
        ' mas... se já existe... não inserir!
        strLocateSelected = "existe = '" & Me.frmfld_refSelecao & qryMMRfilterNew_rst!CodMilitante & "'"
        qrySelecaoExistencias_rst.FindFirst strLocateSelected
        If qrySelecaoExistencias_rst.NoMatch = "" Then
            tblSelecaoDetail_rst!CodMilitante = qryMMRfilterNew_rst!CodMilitante
            tblSelecaoDetail_rst!refSelecaoMaster = Me.frmfld_refSelecao
            lngNumRecords = lngNumRecords + 1
        End If

but I am getting, on the  rst.nomatch statement tye "type mismatch" error

the rst looks OK as well as the search field...

can anyone help?
