Lars I now have it working - using all of the methods (including the simple one that didn't work for my directory). I have looked and looked at the original but cannot see how it is different! Anyhow thank you again for your help.

Thanks for that it has taken me part way as I can certainly now create an order for the items in the directory.
Unfortunately if I try to change the code to <dtml-in objectValues sort=paraNum> <dtml-var sequence-item><br> </dtml-in>
The code breaks telling me that Zope has encountered an error while publishing this resource.
Error Type: KeyError Error Value: para1.paraNum
Doesn't do that with my test... - it works!?! Perhaps try <dtml-var "_['sequence-item']"> But now I've got an idea: Through that construct _every_ doc / method in your folder is rendered! So I think the error occurs in one of your docs / methods, but not in that construct! This can be quite confusing! Also be aware that the method itself is rendered again - but for some (for me quite unclear) reasons it doesn't render the construct recursively - I think that is because the repeatedly rendered method doesn't have elements in objectValues. You can test that by inserting a line: <dtml-in objectValues sort=myprop> <dtml-var "_['sequence-item']"><br> <dtml-else>No elements in list to run through...<br> </dtml-in> It could also be the case that the error occurs in the method when rendered again. So just avoid to render "yourself" again: <dtml-in objectValues sort=myprop> <dtml-unless "_['document_id'] == _['id']"> <dtml-var sequence-item><p><br></p> </dtml-unless> <dtml-else>No elements in list to run through...<br> </dtml-in> Note to use the long winded _['...'] thing for getting a string instead of just "document_id == id" which are methods or somewhat...
