[tw] need help using variables and custom fields in pagewise FET

[Dave Parker]

I think if I keep the value of each tiddler's counting in a custom
field (called "VerseCount") I can solve my problem, even if
"window.fetStartIndex" is changed by another tiddler.  My problem is I
don't know how to properly handle all the different types of variables
here.

I tried adding this before the above FET:
<script>
var CountValue = store.getValue(tiddler, "VerseCount");
</script>

and then change the button code to this

            createTiddlyButton(context.place,"<",null,
                    function(e) {
        CountValue -= window.fetItemsPerPage;
        store.setValue (tiddler.title, "VerseCount", "CountValue");
                window.fetStartIndex = CountValue;
                story.refreshTiddler
(context.viewerTiddler.title,null,true);
                    });
            createTiddlyButton(context.place,">",null,
                    function(e) {
        CountValue += window.fetItemsPerPage;
        store.setValue (tiddler.title, "VerseCount", "CountValue");
                window.fetStartIndex = CountValue;
                story.refreshTiddler
(context.viewerTiddler.title,null,true);
                    });

this doesn't work because I don't really know how to handle the
different uses of variables.

Could someone smart please tell me what I'm doing wrong?


Thanks,
DP
