Any advice on the following problem accepted with thanks: I'm generating a list of data items in a zope page template.The data comes from an ZSQL method and successfully generates a list of items in the database however I have Compilation failures if I try the following: <a href="delete?isbn=<span tal:replace="list/isbn">"isbn"</span>">delete</a> the error returned is " TAL.HTMLParser.HTMLParseError: EOF in middle of construct," What I'm trying to do is construct a query string thus (where isbn is '1234567890'): <a href="delete?isbn=1234567890>delete</a> The delete object (another page template) is (I hope) a tal equivalent to a '<dtml-call delete>' <p tal:define="unused here/deleteMethod" tal:omit-tag=''> thanks in advance for any suggestions: Stu
