I had thought of building the contents as a "sandwich", pulling everything before the 'M23' from one method, then the string 'M23', then the remainder from another method. But I can't save a method that looks like broken DTML, i.e. that ends with '<!--#var '.

Aaahh, yes. I should have thought of this earlier... I use this recently learned trick on an internal system at the office: <!--#in sqlSelectJobOffer--> <!--#var expr="_.getattr(PositionDescriptions, pd_doc_name)(_.None, _)"--> <!--#/in sqlSelectJobOffer--> where PositionDescriptions is a folder in my acquisition hierarchy and pd_doc_name is a column returned in the SQLMethod sqlSelectJobOffer which contains the id of the document I want to insert. Of course, you could hijack the pd_doc_name earlier in the DTML Method and/or stuff it into the REQUEST. --Rob
