The name 'nyhedId' does not exist in the class or namespace

Hej jeg får følgende fejl i linje 68:
The name 'nyhedId' does not exist in the class or namespace 'ASP.nyhed_rediger_temp_aspx'

jeg kan ikke finde fejlen da jeg mener jeg har ramt den rigtig men måske har jeg kigget det forkert sted?

Line 66:     OurConnection = new
Line 67:     SqlConnection(@"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=c:\Inetpub\wwwroot\eHandel\abcd.mdb");
Line 68:     OurCommand = new SqlCommand ("UPDATE nyhed SET nyhedOverskrift = @nyhedOverskrift, nyhedTekst = @nyhedTekst WHERE nyhedId = " + nyhedId, OurConnection);
Line 69:     OurCommand.Parameters.Add("@nyhedOverskrift", SqlDbType.VarChar).Value = nyhedOverskrift.Text;
Line 70:     OurCommand.Parameters.Add("@nyhedTekst", SqlDbType.LongVarChar).Value = nyhedTekst.Text;




Her er koden kan nogen se fejlen:
