Table of contents in Crsytal Reports 2008

Question

Hi,
I have a requirement to create table of contents showing pagenumbers along with the titles in report.I tried using below formula:
WhilePrintingRecords;
StringVar Array catArry;
NumberVar Array pageArry;
IF NOT (GroupName({ARTIST.LAST_NM}) IN catArry) THEN (
Redim Preserve pageArry[UBound(pageArry) + 1];
pageArry[UBound(pageArry)] := PageNumber;
Redim Preserve catArry[UBound(catArry) + 1];
catArry[UBound(catArry)] := GroupName({ARTIST.LAST_NM});
Here grouping should be done on the name of last name. I have created a group also with that. This formula is added in Report header. But i am getting an error stating "A boolean value is required here" while saving it.
I also tried the below formula as an alternative approach:
global stringvar strTOC1;
global stringvar strTOC2;
local stringvar strTemp;
if not InRepeatedGroupHeader then
  ( strTemp := {ARTIST.LAST_NM} + chr(10) ;
  if len(strTemp) + len(strToc1) <= 254 then
    ( strToc1 := StrToc1 + strTemp;
    strToc2 := StrToc2 +
      totext(PageNumber,0) + chr(10) ))
This also gives the same error.
Please let me know if the formulas used are incorrect. Please suggest if there are anyother ways to implement this.
Thanks in advance!

Satya,
In Oracle create a Package with both a Package Head and a Body definition - ORACLE help has acouple examples of this
In the Head you would need to define the REF_CURSOR record you would be using in Crystal. I am copying a simplified version of one of mine here:
The Head definition --
create or replace PACKAGE TST_PROFILE_EXTRACT_RENAME AS
TYPE PROFILE_EXTRACT_REC IS RECORD
(RC_Profile_num_in               TEST.PRFL_NB%type
,Addditional fields are defined here
,Addditional fields are defined here
,Addditional fields are defined here
TYPE PROFILE_EXTRACT_Type IS REF CURSOR RETURN PROFILE_EXTRACT_rec;
PROCEDURE sp_PROFILE_EXTRACT (
PROFILE_EXTRACT_CURSOR IN OUT PROFILE_EXTRACT_TYPE
,IV_PARAMETER_1 IN  PRM_RPT_DFLT.TEST_NUM%TYPE
,IV_PARAMETER_2 IN  VARCHAR2);
END TST_PROFILE_EXTRACT_RENAME;
Body definition --
create or replace PACKAGE BODY TST_PROFILE_EXTRACT_RENAME AS
PROCEDURE sp_PROFILE_EXTRACT (
PROFILE_EXTRACT_Cursor IN OUT PROFILE_EXTRACT_Type
,IV_PARAMETER_1 IN  PRM_RPT_DFLT.TEST_NUM%TYPE
,IV_PARAMETER_2 IN  VARCHAR2 ) IS
--- working variables go here
LV_FILLER_D6                    CHAR(6);
LV_FILLER_H9                   CHAR(9);
LV_FILLER_T14                  CHAR(14);
BEGIN
Code to delete out any existing "old" data rows from a previous execution
COMMIT -- to make sure these do not get picked up in the current execution
Code goes here -- to do full Select and/or PLSQL goes here including the insert to the "temp" table you have defined in structure to ORACLE.
After all processing is done and all updates COMMITTED,
Open the REF_CURSOR to Crystal using a select against your "temp" table as the last piece of code in your SP.
OPEN PROFILE_EXTRACT_Cursor FOR
select
RC_Profile_num_in              
,Addditional fields are defined here
FROM "temp" table
WHERE   - any additional logic you might need (we are using a unique identifier for each report SP in order to allow reuse/multi-threading of our reports)
ORDER BY .....  as necessary for your critera - we are using a counter to make sure we retrieve the rows in the order they are inserted but this may or may not be necessary depending on your data.
END sp_PROFILE_EXTRACT;
END TST_PROFILE_EXTRACT_RENAME;
Searching the web for ORACLE and Stored Procedures returns a number of examples (some good and some otherwise) but this is the model we are using.
Let me know if you have any other questions.
