How to pass parameters to concurrent program report from Forms Personalizn

Question

Hi All,
I am trying to run a report from a menu entry in the AP Invoice entry form. For this I have done the necessary steps of creating the menu entry and am assigning the values for the 2 parameters to a global variable and then launching SRS form.
In SRS form created an action to assign the global variable value to work_order.parameters. I can invoke the SRS OK except that my 2 parameter values appear concatenated in the first parameter itself and are not getting assigned to each of them seperately.
my global variable assignment is as follows :
=${item.inv_sum_folder.vendor_name.value}||'.'||${item.inv_sum_folder.vendor_site_code.value}
and my work_order.parameters value assignment is as follows :
=select nvl(${global.kmg_invalid_po_gv.value}, ${item.work_order.parameters.value}) from dual
It passes parameters OK if i replace custom report with standard AP report. I also made my parameters to be free text (17 character value set) to not validate input, but still no joy.
Any ideas why this is not working ?
Thanks in advance.

As Francois said in his answer:
e.g.:Form A call FORM B
In form A (Button's or menu's Trigger code)
DECLARE
param_list_id  ParamList;     
BEGIN
param_list_id := GET_PARAMETER_LIST('EMPNO');
IF NOT ID_NULL(param_list_id) THEN 
DESTROY_PARAMETER_LIST(param_list_id);
END IF;
param_list_id := CREATE_PARAMETER_LIST('empno');
ADD_PARAMETER(param_list_id, 'EMPNO', TEXT_PARAMETER, EMPNO);
CALL_FORM ( 'FORM B.FMX',HIDE,DO_replace,NO_QUERY_ONLY,param_list_id);and in FORM B create a parameter EMPNO (e.g.: varchar2) in node tree(parameter) and at Form level (e.g. WHEN NEW FORM INSTANCE read parameter-
or you could create a GLOBAL variables
or, still,Global procedure in LIB
