PL/SQL toolkit -- checkbox values in array parameter

Question

I have the following issue that I have been staring at for a couple of hours now and unable to see what’s wrong:
I have a some-what complex PL/SQL application written, with lots of procedures, functions, etc. One of the stored procedures prints a check-box question, where the user has 7 selections to choose from. The results are stored in an ‘array’ of type: TYPE varchar2_tabletype IS TABLE OF VARCHAR2(7) INDEX BY BINARY_INTEGER;
The way the check-boxes are printed to the screen and the values captured is via the following sample code:
-- Assign which check boxes were checked
IF pv_categories.COUNT > 0
THEN
FOR i IN pv_categories.FIRST .. pv_categories.LAST
LOOP
lv_options (pv_categories(i)) := 'checked';
END LOOP;
END IF;
OPEN cursor_categories;
FOR i IN 1 .. 7
FETCH cursor_categories INTO value, item_id;
EXIT WHEN cursor_categories%NOTFOUND;
-- HTML call to open a row exists here
-- Code to print the check-box:
twbkfrmt.p_tabledata ( HTF.formcheckbox('pv_sensitive', item_id, lv_options(i),
'ID="item_id"' ));
Etc…
Then, in another function, I am attempting to print the array results – and I get a data not found error/exception. Please also note that once the user makes a selection of the categories – they do get properly inserted into the database.
Let’s say a user made 4 selections having a value of 1, 2, 3 and 4.
When I print pv_categories(1): 1 gets printed.
When I print pv_categories(2): 2 gets printed.
When I attempt to print pv_categories(3) – (it should exist) – a data not found error results.
Also, when I print to the screen (for testing purposes) pv_categories.count, the result is 5, versus 4. Any ideas as to what I may be doing wrong?

This is not Oracle Forms, just a PL/SQL web application on a server.
I used the following info. to guide me: http://download.oracle.com/docs/cd/B10501_01/appdev.920/a96590/adgweb.htm
However, as already mentioned, I am receiving strange errors at the moment when attempting to 'read' the values stored in the array.
I thought this forum was for any PL/SQL questions? I don't know where else to post, if this isn't intended for that case?
