Using database links in a plsql page process

Question

I am trying to use a database link in a pl/sql page process.
It works fine when I use the link name in the plsql like this:
BEGIN
SELECT 
CARD_ID
into  
:P12_HDR_CARD_NUMBER 
from     [email protected];
But the link name will be coming from a page item (P12_DBLINK) populated as follows:
select db_link d, db_link r from user_db_links; 
I have tried the following and it's not working:
DECLARE
l_link VARCHAR2(30);
BEGIN
l_link :=  :P12_DBLINK;
SELECT 
CARD_ID
into  
:P12_HDR_CARD_NUMBER 
from     fusion.EXM_CC_COMPANY_ACCOUNTS@l_link;
this gives me:
ORA-04052: error occurred when looking up remote object FUSION.EXM_CC_COMPANY_ACCOUNTS@L_LINK.WORLD ORA-00604: error occurred at recursive SQL level 3 ORA-02019: connection description for remote database not found
I thought that maybe the link name was getting appended with .WORLD automatically but the link name already has .WORLD at the end. I tried stripping that off first but the error is the same.
Is there some synatx for this that will work for this? Will I need to use dynamic sql?
Any suggestions are most appreciated.
thanks,
john
