Invoking PL/SQL function (via DB Adapter) with in parameter (BPEL newbie)

Question

Hi!
Using: JDeveloper: 10.1.3.3.0, OAS: 10.1.3
I'm new to BPEL, and now I have a simple problem:
anyway to pass in parameter value with PL/SQL function call via DB Adapter?
PL/SQL function like this:
>>
create or replace function f_test_bpel (p_in in number)
return number
is
begin
return p_in;
end;
>>
For example (audit part of invoke in BPEL Console. Output always null :( ):

Adding more to what 'Arcturus' has put across :
1) You can check your input & output arguments to a PL/SQL function/procedure using an assign activity, in which you tend to assign a source variable to a target variable.
Here, you can check to see, if the input & output to the DB Adapter are correct, if not, you can always recreate the adapter.
2) You can also check the schema of the PL/SQL function, to check if it has the right inputs & outputs.
It'd be a .xsd file in the format of <SCHEMA_NAME-OF-FUNCTION.xsd> viz. SCOTT_EMPDETAILS.xsd
