Execute Query by using LOV (List Item)

Question

Hello Everyone,
I did research on how to use List Item with Query but i am still confused since i am a new to the FORM.
I have created a form where user enters
Start Date: -- this field user can just type the date
End Date: -- this field user can just type the date
Violence: -- this is my List Item (Drop down Menu) where user select the code
once they select the parameter i have created "Execute" button and it will give number of violence within the date range. the query is giving me right number or violence but then i need to drill down to details.
so i created a trigger when user double click on the number ( result number) it will pop up another window and display the details
For example:f_name, l_name, ssn etc...
Now, my problem is when i double click on (Text Item) it. Its not giving me the number of records that i have get when i execute at the first by using date range and violance code.
This is the step that i have use:
when user click Execute button the PL/SQL code:
Query_step1(:start_date,:end_date,:violations);
when user double click on Text Item once they have the number this is what i have used code for PL/SQL
begin
     go_block('xxhc_hearings_rpt_v');
     set_block_property('xxhc_hearings_rpt_v',default_where,'hearing_result = '||'''TERMINATE'''||'and violation '||''||:violations||''||'and propose_term_dt between '||''''||:start_date||''''||' and '||''''||:end_date||'''');
     execute_query;
end;
So please anyone can give me little direction that will be a great help.
Thank You.

Use the system variable LAST_QUERY to check that you SQL is valid. Assign it to a temp field in the block and check it out.
