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.

Hi all, I'm trying to get something working that displays a sequence from a database and provide next-sequence and previous-sequence buttons. What is different from the online documentation is that I want both the buttons at the end of a sequence block.
eg, I want, <!--#in my_sequence size=5 orphan=1 start=query_start--> . ..the values from my_sequence...
<!--#if previous-sequence--> previous button (batch of five). <!--#/if--> <!--#if next-sequence--> next button (batch of five) <!--#/if--> <!--#/in-->
whereas the Zope docs imply this format, <!--#in my_sequence size=5 orphan=1 start=query_start--> <!--#if previous-sequence--> previous button (batch of five). <!--#/if-->
..the values from my_sequence...
<!--#if next-sequence--> next button (batch of five) <!--#/if--> <!--#/in-->
The problem is that the previous-sequence button is not shown (at all). The docs say 'previous-sequence:: the variable is true when the first element is displayed, and when the first element displayed is not the first element in the sequence'
This *seems* to imply that previous-sequence can only be used at the beginning of a sequence...(and presumably that next-sequence can only be used at the end of a sequence).
Is this right?
