[Zope] problem

Hi, When does the next-sequence-item exists? Does it only exists in the sequence-end face? I want to provide the following: Next Line1 Line2 Line3 ... Next Clicking on 'Next' will move to the next result set. The problem is that I seem not be able to put a Next link on top of the result set, because 'next-sequence-size', 'next-sequence' only exist in the 'end-sequence' phase. Is their a way to solve this? Probably there is, but I can't find it at the moment. thanks in advance, Tom.
