Problemer med Update i access database, får fejl i C# script

Hej jeg har prøvet at følge en vedledning i at lave en update men får denne fejl.

The type or namespace name 'strSQL' could not be found (are you missing a using directive or an assembly reference?) i:

strSQL updateCmd = "UPDATE nyhed SET nyhedOverskrift = @nyhedOverskrift, nyhedTekst = @nyhedTekst WHERE nyhedId = " + Request.QueryString["ID"];

Se hele koden her:
<%@ Page Language="C#" ContentType="text/html" ResponseEncoding="iso-8859-1" debug="true" %>
<%@ import Namespace="System.Data" %>
<%@ import Namespace="System.Data.OleDb" %>
<% string title; title = "Indsæt nyheder"; %>
<script runat="server">

    void Page_Load(object Sender, EventArgs E)
    {
    string strConnection;
            string strSQL;
            OleDbConnection objConnection;
            OleDbCommand objCommand;
            strConnection =@"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=c:\Inetpub\wwwroot\eHandel\abcd.mdb";
            objConnection = new OleDbConnection(strConnection);
            objConnection.Open();
            strSQL = "SELECT * FROM nyhed WHERE nyhedId = " + Request.QueryString["ID"];
            objCommand = new OleDbCommand(strSQL, objConnection);
            dgData.DataSource = objCommand.ExecuteReader(CommandBehavior.CloseConnection);
            dgData.DataBind();
           
            objConnection.Close();

    }
    void update(object Sender, EventArgs e){
   
    string strConnection, strSQL;
            OleDbConnection objConnection;
            OleDbCommand objCommand;
            strConnection =@"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=c:\Inetpub\wwwroot\eHandel\abcd.mdb";
            objConnection = new OleDbConnection(strConnection);
            objConnection.Open();
            strSQL updateCmd = "UPDATE nyhed SET nyhedOverskrift = @nyhedOverskrift, nyhedTekst = @nyhedTekst WHERE nyhedId = " + Request.QueryString["ID"];
            SqlCommand myCommand = new SqlCommand(updateCmd, myConnection);
            myCommand.Parameters.Add(new SqlParameter("@nyhedOverskrift", SqlDbType.NVarChar, 11));
            myCommand.Parameters.Add(new SqlParameter("@nyhedTekst", SqlDbType.NVarChar, 11));
            objCommand = new OleDbCommand(strSQL, objConnection);
            dgData.DataSource = objCommand.ExecuteReader(CommandBehavior.CloseConnection);
            dgData.DataBind();
           
            objConnection.Close();

    }
        public void dgData_Edit(object sender, EventArgs e)
    {
        dgData.EditItemIndex = (int)e.Item.ItemIndex;
        Databind();
    }

    public void dgData_Cancel(object sender, EventArgs e)
    {
        dgData.EditItemIndex = -1;
        Databind();
    }


</script>


<form runat="server">

<h3>Rediger nyheder</h3>
<asp:datagrid id="dgData" runat="server" OnEditCommand="update" OnCancelCommand="dgData_Cancel" OnUpdateCommand="dgData_Update" DataKeyField="nyhedId">

  <Columns>
    <asp:EditCommandColumn EditText="Edit" CancelText="Cancel" UpdateText="Update" />
  </Columns>

</ASP:DataGrid>

</form>

Håber der er en der kan hjælpe?
