[Zope] standard_error_message in 2 places

i have a folder, devel, as a subfolder of '/'. i have also 2 set of standard_html_header[footer] and standard_error_message in the 2 folders. the situations is: while the corresponding standard_html_header[footer] work well, the standard_error_message under devel folder doesn't work. standard_error_message under '/' is the one always returned to the browser. is there an explaination of this situation? or do I misunderstand the concept of acqusition? thanks for your answers -- 'Life is like boxes of chocolate, Forrest.
