[Zope] next-sequence and previous-sequence help..

[Phil Harris]

Hi Tone,


Couldn't you copy the contents of the var's you need into the REQUEST object
for use later in the script,

e.g.

<!--#call
"REQUEST.set("mynext_sequence_start_index",next-sequence-start-index)-->
.
.
.
.
<!--#var mynext_sequence_start_index-->

I think you'll get the idea from this.
