Error with report - pkg and bind var

Question

Hi to all,
i'm writing some report and i found a strange isssue.
I would like to retrieve some data using packages.
So, something like select dbms_xxxx(var1, var2, var3) from dual;
I would like to pass through bind vars the value per each variable.
I used :var1 and also &var1 to be secure..
if i use select dbms_xxxx(':var1', ':var2', ':var3') from dual;
it gives me error about the apex, so i changed it in
select dbms_xxxx(par1 => :var1.....
Now it gives a problem with the parenthesis. But they are right!
Any ideas? A possible limit of developer?
By the way.. latest sqldev version.
Thanks
Acr

Example:
SELECT DBMS_METADATA.GET_DDL(
object_type => upper(&object_type),
object_name => upper(&object_name),
schema => upper(&schema)) DDL
FROM DUAL;
This i what i get.
Error: ORA-00907 MISSING RIGHT PARENTHESIS
using &var or :var
