Error while doing Bulk Collect to a table type

Question

I'm using a Table type to accumulate resultset from a loop and finally return the records in the table type as a ref cursor to the front end.
But when I'm using Bult collect to insert into the table type object it keeps throwing an error
'PLS-00597: expression 'TAB_CALENDAR_AVAIL_RESULTSET' in the INTO list is of wrong type'. Can someone help me to let me know what could be the reason for this error. I'm not able to proceed further, please help.
Here is the code.
CREATE OR REPLACE PACKAGE hotel

TYPE type_calendar_avail is RECORD(
HOTEL_ID AVAILABILITY_CALENDAR.hotel_id%TYPE,--varchar2(4), --AVAILABILITY_CALENDAR.hotel_id%TYPE,

Answer 1

1. put tags [co[/b][b]de] and [co[/b][b]de] around your code, so it's readable
B. what does "hotel.get_unittype_cond (v_unit_cond, sorcowner)" actually retun?
and third, try this for the array declaration:
tab_calendar_avail_resultset type_calendar_avail_resultset := type_calendar_avail_resultset ; () ;
