Hi,
<i>Regarding your first error in basket.htm</i>
You will have to use the application class <b>CL_BSP_TUTORIAL</b>.
To do this just double-click on the bsp application name where you defined <b>Navigation Requests</b> in the first tutorial, click on the <b>Properties</b> tab and in the field next to <b>Application Class</b> put the application class name as : <b>CL_BSP_TUTORIAL</b>
<i><b>This should solve the second error too...just check and let us know...</b></i>
Hope this helps.
