Passing values from and to workflow container

Question

Hi Guys,
             I am reading and writing back into the workflow container element from task container using FM.
But its not writing back the values into workflow container.
here is my code.
swc_get_element container 'TripNumber' trip_no.   
Fetch Personal No. from Trip No.                
  SELECT SINGLE pernr FROM ptrv_head INTO l_pernr  
    WHERE reinr = trip_no.                                                                               
IF sy-subrc NE 0.                                 
  EXIT.                                            
ENDIF.                                                                               
Fetch Employee Name                             
SELECT SINGLE ename FROM  pa0001 INTO l_ename      
       WHERE  pernr = l_pernr                      
       AND    endda  >= sy-datum                   
       AND    begda  <= sy-datum.                  
Fetch Employee Email id                         
select single usrid_long from pa0105 into l_email 
   where pernr = l_pernr                           
     and usrty = '0010'                            
     and endda  >= sy-datum                        
     AND begda  <= sy-datum.                       
Set Personal No.                          
swc_set_element container 'Pernr1' l_pernr. 
Employee Name                             
swc_set_element container 'Ename' l_ename.  
Email ID                                  
swc_set_element container 'Email' l_email   
Am I missing anything here.
Thanks

Hi,
I faced the same issue and i found that it is not sufficient to just have proper bindings and using macros with exact container names.
You need to create IMPORT and EXPORT parameters for that METHOD with names matching with container element names. Once you do this, you see a GREEN binding icon right below the BO and Method name in the TASK. Click that icon and create binding between TASK and METHOD.
This should resolve your problem.
All - Please correct me if am wrong as i am new to the workflow.
Thanks,
