I have made my extension. It worked perfectly well in development. I've even packaged it OK. It's creating menus correctly, and putting constituent files in the right place. But when I click on the menu (under server behaviors) I get this error message.

"Error in server behavior hide_metas_asp.htm: the search string was not found or it was incorrectly formed. Make sure there is a comment at the top of the file in this format: <!-- search:"string to find"--> Example: <!-- search:"rs.Request(\"r"-->

What does it all mean?
