Creating a SVG Pie Chart With Different Portion Linking To Different URL

Question

Is it possible to create a SVG pie chart in which different portion will point to different URL. on HTML DB version 1.5.1.00.12
For example i've tried something like this:
on page 20 i have a svg pie chart
select
'f?p=&APP_ID.:21:#APP_SESSION#::::P21_DD_SALESORG:'||region,region,code from demo_region;
i have a query in page 21 like this:
select country from demo_country where region= :P21_DD_SALESORG;
so when i click on a particular region on the pie chart on page 20 the value of item
P21_DD_SALESORG on 21 should be set.
but the value of P21_DD_SALESORG is always getting passed as NULL from the pie chart.
I've tried it on HTML DB version 1.5.1.00.12
Look for an early reply
Thanks & Regards,
Rupak

hi user445907--
your link column in your chart query seems to us the correct syntax, so i'd imagine the issue is with your data/query or the item name in question...
check the query and data: make sure your query returns valid values to be passed of to P21_DD_SALESORG. if so, you should see your links correctly formed as you hover your mouse over the individual slices. if your links look good then check your item names.
item names: if your links above look okay, then might you be setting the value of the incorrect item? please confirm that. after clicking a pie slice to get to page 21, check to see that P21_DD_SALESORG is correctly set by clicking the Session link in the developer toolbar.
basically, i'm suggesting that because your link column in your query looks okay, you'd want to see at what point the NULL value is being passed/set. try tracing things from the chart query over to page 21 (and try going backwards if you have to). if you can't find the disconnect, please feel free to set up an example on an instance, where i can take a look.
thanks,
