Query Invoices based on checked sites WHEN_BUTTON_PRESSED

Question

Hello,
I am newbie to Oracle Forms, Please correct me if iam wrong.
Requirement: I have a Master-detail Block with Vendors and Vendors Sites. When i query a vendor, all his sites also will be listed. Against each site there is a check box. When i select a site and hit 'Invoice' Button all the invoices for that site have to be returned. For simplicity i am trying only one site per vendor first.
What i already tried: In WHEN_BUTTON_PRESSED trigger i wrote
BEGIN
IF CHECKBOX_CHECKED(:po_vendor_sites_all.vendor_site_id)
THEN
:GLOBAL.SITES:=:po_vendor_sites_all.vendor_site_id;
END IF;
fnd_function.execute(FUNCTION_NAME=>'STAP_SITE_INVOICES',
OPEN_FLAG=>'Y',
SESSION_FLAG=>'N',
OTHER_PARAMS=>':GLOBAL.SITES');
END;
In Invoices datablock i joined it in default where clause. But i am getting
FRM-40105 (Unable to resolve reference to item Site_id#)
FRM-40815 (Variable Global.sites does not exist)
Please help me how to go about writing when_button_pressed trigger and checkbox_checked logic. Any help is highly appreciated.
Thanks.

Hello Dora
"In the block where you display the invoices list , change the where clause as
where instr(:GLOBAL.SITES, vendor_site_id) > 0 "
What exactly will this where clause acheive. It is not behaving as expected.
The back end query which i am trying to represent in front end on forms is something like this
select spo.vendor_id,ssite.vendor_site_id, sinv.invoice_id from xxlm_stap_invoices_all SINV, xxlm_st_po_vendors SPO, xxlm_st_po_vendor_sites_all SSITE
where spo.vendor_id=ssite.vendor_id
and spo.vendor_type_lookup_code='SUPPLIER'
and ssite.vendor_site_id=sinv.vendor_site_id(+);
Here i have around 50 rows. There are 20 supplier with 2 or 3 sites each. Few of these sites have invoices and few dont.
So when i tried changing the where clause to
vendor_site_id=:gloabl.sites
and instr(:GLOBAL.SITES, vendor_site_id) > 0
but of no use. I appreciate your time in responding me.
Please help me in connecting the sites and invoices properly. (I want to check multiple sites at once and fetch all the invoices that are relavant to them)
Thanks
