[Zope] here/content

Can someone tell me how 'here/content' is translated in these lines? <span tal:define="stx python:modules['Products'].PythonScripts.standard.structured_text; the_text here/content" tal:content="structure python:stx(the_text)"> The structured text goes here. </span> When I use the URL 'www.mysite.org' the above resolves fine, but if I use 'www.mysite.org:8080/mysite' I get a 'Resource not found' when selecting the same link from the homepage of the same site. Is there something I've overlooked? -- John
