<p>I have created a function for this button and I still continue to get this compilation error message.  Does anybody have any ideas on what I can try? Thank you!!!</p>

<pre><code>    aspx page -  
    &lt;asp:Button ID="btnSubmitOthers" runat="server" Text="Submit"  onclick="btnSubmitOthers_Click" /&gt;

    aspx.designer.cs page -
    /// &lt;summary&gt;
    /// btnSubmitOthers control.
    /// &lt;/summary&gt;
    /// &lt;remarks&gt;
    /// Auto-generated field.
    /// To modify move field declaration from designer file to code-behind file.
    /// &lt;/remarks&gt;
    protected global::System.Web.UI.WebControls.Button btnSubmitOthers;

    and this is what I hae on the aspx.cs page:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Data.SqlClient;
using System.Configuration;
using System.Web.Configuration;

protected void btnSubmitOthers(object sender, EventArgs e)
    {
        var currUser = DB.Users.Where(u =&gt; u.GUID == Request.Cookies["User"].Value).Single();
        var rubric = new Rubric
        {
            PromptID = Convert.ToInt32(lblPromptID.Text),
            CreatedOn = DateTime.Now,
            Reflection = Convert.ToInt32(ddlOthersReflection.SelectedValue),
            Awareness = Convert.ToInt32(ddlOthersAwareness.SelectedValue),
            Commitment = Convert.ToInt32(ddlOthersCommitment.SelectedValue),
            Comment = tbOthersComments.Text,
            UserID = currUser.id
        };
        DB.Rubrics.InsertOnSubmit(rubric);
        var prompt = DB.Prompts.Where(p =&gt; p.id == rubric.PromptID).Single();
        prompt.LockedAt = null;
        prompt.LockedBy = null;
        DB.SubmitChanges();
        Prompt.ProcessPromptsToFinal(); 
        //it would be better off as a service.
        Response.Write "Submitted";

    }

<p>Any approaches you can come up with are appreciated! </p>
