[Zope] plone styles in my zpt macros file

[Exteam]

hi,
i have installed plone in my linux box which installed
zope.
now i have a folder abc in root (/abc).
i have a ZPT macros file in abc starting with 
the first  line as:
--div metal:define-macro="my_macro1"--

now i want to call plone's header & footer files
written in dtml. these files are stored in the
/portal_skins/plone_templates .
how do i call them in my ZPT macros file?
i had used 

--div tal:content="structure
here/standard_html_header"--

to call the header.it actually calls the header, but
gives style sheet errors in the page like 
"document.all.content.style is not null or an object".
More over it doesn't display any of the content
present in the ZPT macros file.
But in the same way another dtml method in the same
directoy called check_status does the same job.
ie calls the same header file using the following
statement
"--dtml-var standard_html_header--".
It works perfeclty here.
what is the problem? why doesn't it work in  the ZPT
file?
Please help me
thanks
exteam
