[Zope] Records marshalling: trying to including a list within a record

Hi, Can anyone give me ideas on solving the following problem... Im trying to pass information in a form using :records. One item in each record is a list I wish to pass as a list and use <dtml-in bob> to display the list contents. I have tried all sorts of variations... <input type="hidden" name="my_record.bob:records:list" value="<dtml-in bob><dtml-var sequence-item></dtml-in>"> and... <input type="hidden" name="my_record.bob:list:records" value="<dtml-in bob><dtml-var sequence-item></dtml-in>"> Anything I try just places the whole of "bob" as one item in a list. eg if bob was ['this ','is ','bob']. The list in the record passed using the form would be ['this is bob']. Thanks for any ideas in advance. Richard
