Error while creating Group

Question

Hi All,
We have a typical scenario.
In our application we have a form 'Cust_fmb' which will give count of records for customer. We are populating the customers group using following query.
rg := create_group_from_query('custgrp','
          select cust_id rlabel,cust_id rvalue
          from custschema.customer_tab
When user login into our application and open that Cust_fmb form , form is populating the customer group but when user login into our application and opens and access multiple forms and then opens Cust_fmb forms
we are getting the error 'FRM-41072: Cannot create Group custgrp'.
We are not able to find out the cause why we are getting this error.
Please helps us,
Thanks in advance,
maddy

Thanks for the response
My code as below
PROCEDURE POPULATE_CUST_GROUP IS
  rg recordgroup;      
  nn number;
  rquery varchar2(600);
BEGIN
     rg := find_group('custgrp');
     if not id_null(rg) then
          delete_group(rg);
     end if;
rg := create_group_from_query('custgrp','
          select cust_id rlabel,cust_id rvalue
          from custschema.customer_tab
nn := populate_group(rg);
if nn <> 0 then
     message('Populate group had error ');
end if;
populate_list('MAIN.GROUP_ID',rg);
END;
Can any one tell me why do I get this error. Please..
Thanks,
maddy
