How to exclude 'Saturday' and 'sunday' In APEX 4.1 count(*)

Question

Hi everyone am using APEX 4.1,
The Leave_transaction Table has the following Fields,
1.Leave_id
2.Emp_name
3.From_date
4.To_date
5.Remaining_days
The Emp_Master Table has the following columns,
1.Emp_id
2.Emp_Name
3.Remaining_days
select count(*) into days from (select dt
from(
    select to_date(:p1_from_date, 'DD-Mon-YYYY') + rownum -1 dt
        from dual
connect by level <= to_date(:p1_to_date, 'DD-Mon-YYYY') - to_date(:p1_from_date, 'DD-Mon-YYYY') + 1)
where to_char(dt,'fmday') not in ('sunday','saturday') dual;
If the Dates is between from_date and To_date comes in Saturday and sunday , it should exclude and return the count(*) remaining dates,
For example,
If the From_date is 04-may-2012'
and To_date is 08-may-2012,
Here the dates 5th may and 6th may are "saturday" and "sunday"
Then the remaining dates are(excluding sat,sunday and dates in holiday_table),
04-may-2012,
07-may-2012
08-may-2012.
so
count(*)
3I am using the above code but still it returning 5,
I think this
..where to_char(dt,'fmday') not in ('sunday','saturday')
code is not working.
Can anyone help me to solve my Issue.

Hi theoa,
Actually this is my full code,
declare
      days          number(3);
     ex_days          emp_master.remaining_days%type;
      new_rem_days  emp_master.remaining_days%type;
    begin
      select count(*)
      into   days
      from   (select dt
                from   (select to_date (:p1_from_date, 'DD-Mon-YYYY',
                              'NLS_DATE_LANGUAGE=''english''')
                       + rownum - 1 dt
                   from   dual
                    connect by level <=
                   to_date (:p1_to_date, 'DD-Mon-YYYY',
                         'NLS_DATE_LANGUAGE=''english''')
                   - to_date (:p1_from_date, 'DD-Mon-YYYY',
                           'NLS_DATE_LANGUAGE=''english''')
                   + 1)
               where  rtrim(to_char(dt,'fmDay', 'NLS_DATE_LANGUAGE=''english''')) not in
                   ('Sunday','Saturday')
               minus
               (select holiday_start
             from   holiday_master)) dual;
apex_application.g_print_success_message := 'Hi '||:APP_USER||' '||'You are applied leave for'||' ' || days||' ' ||'days';    
select remaining_days
     into   ex_days
    from   emp_master
     where  upper(emp_name) = upper(:APP_USER);
     new_rem_days := ex_days - days;
     update emp_master
     set    remaining_days = new_rem_days
     where  upper(emp_name) = upper(:APP_USER);
     update leave_transaction
     set    remaining_days = new_rem_days
     where  upper(emp_name) = upper(:APP_USER)
     and    leave_id=
              (select max(leave_id)
               from   leave_transaction);
   end;The select statement which i mentioned above is working fine in database but not working in PAEX application.
