Custom controls are not registered

Question

I try to register my user controls in the webconfig file because I get an Element, there is no error, but I get the following error when I try to register them in webconfig:

Invalid or missing attributes found in the tagPrefix entry. For user control, you must also specify 'tagName' and 'src'. For custom control, you must also specify 'namespace', and optionally 'assembly'

The following is the code in the webconfig file:

<pages>
  <controls>
    <add tagPrefix="asp" namespace="System.Web.UI" assembly="System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />
    <add tagPrefix="asp" namespace="System.Web.UI.WebControls" assembly="System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />
    <add tagPrefix="IPAMControl" tagName="contact_us" namespace="IPAM.Website.Controls" src="~/controls/contact_us.ascx" />
    <add tagPrefix="IPAMControl" tagName="erh_list" namespace="IPAM.Website.Controls" src="~/controls/erh_list.ascx" />
    <add tagPrefix="IPAMControl" tagName="header" namespace="IPAM.Website.Controls" src="~/controls/header.ascx" />
    <add tagPrefix="IPAMControl" tagName="footer" namespace="IPAM.Website.Controls" src="~/controls/footer.ascx" />
    <add tagPrefix="IPAMControl" tagName="main_tnavbar" namespace="IPAM.Website.Controls" src="~/controls/main_tnavbar.ascx" />
    <add tagPrefix="IPAMControl" tagName="program_header" namespace="IPAM.Website.Controls" src="~/controls/program_header.ascx" />
    <add tagPrefix="IPAMControl" tagName="program_list" namespace="IPAM.Website.Controls" src="~/controls/program_list.ascx" />
    <add tagPrefix="IPAMControl" tagName="signup_section" namespace="IPAM.Website.Controls" src="~/controls/signup_section.ascx" />
    <add tagPrefix="IPAMControl" tagName="speaker_list" namespace="IPAM.Website.Controls" src="~/controls/speaker_list.ascx" />
    <add tagPrefix="IPAMControl" tagName="track" namespace="IPAM.Website.Controls" src="~/controls/track.ascx" />
  </controls>
</pages>

Pages that have this problem also link to MasterPages, if that matters at all:

<%@ Page Language="C#" AutoEventWireup="true" MasterPageFile="~/programs/MasterProgram.master" CodeBehind="~/programs/wim2011/default.aspx" Inherits="IPAM.Website.programs.wim2011._default" %>

and each one is within its own folders.

Please, help.
