My queries executes twice :s

[iste]

When I run my code (which doesn't have any loops) , the data is inserted into the database two times.

So when I run one query, I get two lines in the database.

This is the code where the queries are executed:

Try
            connection = New KobleTilDB
            con = connection.KobleTilDB
            
            sp1 = "INSERT INTO Kontaktinfo (Fornavn, Etternavn, Adresse, Postnr, Tlf, Mob, Mail) VALUES('" & ansatt.fnavn & "', '" & ansatt.enavn & _
            "', '" & ansatt.adr & "', '" & ansatt.pnr & "', '" & ansatt.tlf & "', '" & ansatt.mob & _
            "', '" & ansatt.epost & "')"
 
            cmd = New OdbcCommand(sp1, con)
 
            cmd.ExecuteNonQuery()
 
 
            sp3 = "SELECT Navn_id FROM Kontaktinfo " & _
            "WHERE Fornavn = '" & ansatt.fnavn & "'" & _
            "AND Etternavn = '" & ansatt.enavn & "'" & _
            "AND Adresse = '" & ansatt.adr & "'" & _
            "AND Postnr = '" & ansatt.pnr & "'" & _
            "AND Tlf = '" & ansatt.tlf & "'" & _
            "AND Mob = '" & ansatt.mob & "'" & _
            "AND Mail = '" & ansatt.epost & "' "
 
            cmd = New OdbcCommand(sp3, con)
            
            Dim navnid As Integer = 0
 
         
            cmd.ExecuteNonQuery()
 
            reader = cmd.ExecuteReader
 
            If reader.Read Then
                If reader.IsDBNull(0) Then
                    navnid = 0
                Else
                    navnid = reader.GetInt32(0)
                End If
            End If
 
            sp2 = "INSERT INTO Admin (Navn_id, Tittel) VALUES('" & navnid & "', '" & ansatt.stilling & "')"
 
            cmd = New OdbcCommand(sp2, con)
            cmd.ExecuteNonQuery()
 
        Catch oex As OdbcException
            Throw New Exception("Feil i databasen" & oex.Message.ToString)
        Catch ex As Exception
            Throw New Exception("Feil i koden" & ex.Message.ToString)
 
        End Try

I have Three queries, and two of them are inserting values into two different tables.

Why does the values get inserted two times in each table?
