Hi,

This is my code to check if a date and a time both exist in a table:
------------------------------------------------------------------
        Dim rsVal2 As ADODB.Recordset
        Dim sSQL2 As String
       
        Dim strDate As Date
        Dim strRoom As String
        Dim strSubjectName As String
        Dim strSubjectID As String
        Dim strDay As String
        Dim strStartTime As String
        Dim strEndTime As String
        Dim i As Short
        Dim strYear As String

        strDate = txtDayDateRooms.Text
        strRoom = cmbViewRooms.Text
        strSubjectName = cmbSubjectRooms.Text
        strSubjectID = txtSubjectIDRooms.Text
        strDay = cmbDayRooms.Text
        strStartTime = cmbStartTimeRooms.Text
        strEndTime = cmbEndTimeRooms.Text

'**** CHECK IF TIMETABLE TIME ALREADY EXISTS ******

'Query check if new time already exists in time table.
sSQL2 = "SELECT tblSubjectSchedule.Subject_ID, tblSubjectSchedule.Date_Sch, tblSubjectSchedule.Time_Start, tblSubjectSchedule.Location,
tblSubjectSchedule.Day_Sch " & _
"FROM tblSubjectSchedule " & _
"WHERE tblSubjectSchedule.Subject_ID='" & strSubjectID & "' " & _
"AND tblSubjectSchedule.Location='" & strRoom & "' " & _
"AND tblSubjectSchedule.Day_Sch='" & strDay & "' "
'"AND tblSubjectSchedule.Date_Sch=#" & Format(strDate) & "#"
'"AND tblSubjectSchedule.Time_Start= #" & Format(strStartTime) & "#" <----THESE TWO LINES ARE WHAT ARE
CAUSING THE PROBLEM

rsVal2 = m_Conn.Execute(sSQL2) 'Execute query.

if Not rsVal2.EOF Then
            i = 0
            rsVal2.MoveFirst() 'Move to the first record.

            While Not rsVal2.EOF

                rsVal2.MoveNext() 'Move to the next record.
                i = i + 1
            End While
        End If

        If i = 0 Then
            MsgBox("THERE ARE NO RECORDS")
        End If

        If i > 0 Then
            MsgBox("THERE ARE RECORDS")
            Exit Function
        End If

------------------------------------------------------------------

If the date and time exist then i cant add new details in. If there are no records for the date and time, then i can add in.The query is where the problem is, but i think my date and time formatting is incorrect

How do i do this? My code doesnt seem to recognise the date or time when looping through, and always works as if there are no records for date and time, when i know for
a fact in my Access DB that there is!!

Thanks, im in dire straits trying to get this working, hence the 500 points.

Thanks
