OK, I have a standard_html_header for my site that uses the following <dtml-with "PARENTS[0]"> <title><dtml-var head_title></title> <META NAME="keywords" CONTENT="<dtml-var meta_keywords>"> <META NAME="description" CONTENT="<dtml-var meta_description>"> <META NAME="author" CONTENT="<dtml-var meta_author>"> <META NAME="copyright" CONTENT="<dtml-var meta_copyright>"> <dtml-var head_javascript> <snipped rest of document> <dtml-var id> </dtml-with> In this way, the properties of the ZClass (into which the standard_html_header is placed) are used for the for the meta author/copyright/keywords/description/javascript. All of those that I just mentioned work perfectly well, with the correct property being inserted, however, <dtml-var id> results in the id of the parent folder of standard_html_header being inserted, instead of the id of the zclass. Could anyone point out how I can get hold of the zclass id? thanks very much tim
