Select List - checkbox not working properly

Question

Hi,
Can anyone help? I'm able to insert one record into the table with the code listed below, if I select only one checkbox. I get this error message, if I select more than one checkbox: ORA-01722: invalid number ORA-02063: Error ERR-1003 Error executing computation query . Note - Employee number is numeric in table. This is my select list/checkbox field being used in application. Thanks.... Elaine
Procedure being used is:
create or replace procedure "SAF_INSERT_MEETING_RECORDS"(
EMPNUMBER_in IN SAF_MEETING_INFO_V.EMPNUMBER%TYPE,
COURSEID_in IN SAF_MEETING_INFO_V.COURSEID%TYPE,
TRAINDATE_in IN SAF_MEETING_INFO_V.TRAINDATE%TYPE,
HOURSTRAINED_in IN SAF_MEETING_INFO_V.HOURSTRAINED%TYPE,
NEXTTRAINDATE_in IN SAF_MEETING_INFO_V.NEXTTRAINDATE%TYPE,
DATEADDED_in IN SAF_MEETING_INFO_V.DATEADDED%TYPE,
ADDEDBY_in IN SAF_MEETING_INFO_V.ADDEDBY%TYPE,
DATEMODIFIED_in IN SAF_MEETING_INFO_V.DATEMODIFIED%TYPE,
MODIFIEDBY_in IN SAF_MEETING_INFO_V.MODIFIEDBY%TYPE,
CURDEPT_in IN SAF_MEETING_INFO_V.CURDEPT%TYPE,
CURDEPTDESC_in IN SAF_MEETING_INFO_V.CURDEPTDESC%TYPE,
SEQNUM_in IN SAF_MEETING_INFO_V.SEQ_NUM%TYPE)
is
myHoursTrained NUMBER;
mySeq NUMBER;
vCHECKBOXES APEX_APPLICATION_GLOBAL.VC_ARR2;
BEGIN
vCHECKBOXES := APEX_UTIL.STRING_TO_TABLE(EMPNUMBER_in);
myHoursTrained := TO_NUMBER(HOURSTRAINED_in);
FOR i IN 1..vCHECKBOXES.COUNT
LOOP
BEGIN
SELECT SAF_MEETING_SEQ.nextval
INTO mySeq
FROM dual;
END;
INSERT INTO SAF_MEETING_INFO_V
(EMPNUMBER,COURSEID,TRAINDATE,HOURSTRAINED,NEXTTRAINDATE,DATEADDED, ADDEDBY,DATEMODIFIED,MODIFIEDBY,CURDEPT,CURDEPTDESC,SEQ_NUM)
VALUES
(vCHECKBOXES(i) , COURSEID_in, TRAINDATE_in, myHoursTrained, NEXTTRAINDATE_in, SYSDATE,
ADDEDBY_in, DATEADDED_in, MODIFIEDBY_in, CURDEPT_in, CURDEPTDESC_in, mySeq);
END LOOP;
END;

varad,
Thank you so much for your response. I had a few issues with numeric vs character data that I needed to address. I was able to resolve them all, based on the information you provided. I'm posting my new working code. Thanks again. Elaine
Working code is:
CREATE OR REPLACE procedure "SAF_INSERT_MEETING_RECORDS"(
EMPNUMBER_in IN VARCHAR2,
COURSEID_in IN SAF_MEETING_INFO_V.COURSEID%TYPE,
TRAINDATE_in IN SAF_MEETING_INFO_V.TRAINDATE%TYPE,
HOURSTRAINED_in SAF_MEETING_INFO_V.HOURSTRAINED%TYPE,
NEXTTRAINDATE_in SAF_MEETING_INFO_V.NEXTTRAINDATE%TYPE,
DATEADDED_in IN SAF_MEETING_INFO_V.DATEADDED%TYPE,
ADDEDBY_in IN SAF_MEETING_INFO_V.ADDEDBY%TYPE,
DATEMODIFIED_in IN SAF_MEETING_INFO_V.DATEMODIFIED%TYPE,
MODIFIEDBY_in IN SAF_MEETING_INFO_V.MODIFIEDBY%TYPE,
CURDEPT_in IN SAF_MEETING_INFO_V.CURDEPT%TYPE,
CURDEPTDESC_in IN SAF_MEETING_INFO_V.CURDEPTDESC%TYPE,
SEQNUM_in IN SAF_MEETING_INFO_V.SEQ_NUM%TYPE
is
mySeq NUMBER;
vCHECKBOXES APEX_APPLICATION_GLOBAL.VC_ARR2;
BEGIN
vCHECKBOXES := APEX_UTIL.STRING_TO_TABLE(EMPNUMBER_in);
FOR i IN 1..vCHECKBOXES.COUNT
LOOP
BEGIN
SELECT SAF_MEETING_SEQ.nextval
INTO mySeq
FROM dual;
END;
INSERT INTO SAF_MEETING_INFO_V
(EMPNUMBER,COURSEID,TRAINDATE,HOURSTRAINED,
NEXTTRAINDATE,DATEADDED,
ADDEDBY,DATEMODIFIED,MODIFIEDBY,CURDEPT,CURDEPTDESC,SEQ_NUM)
VALUES
(to_number(vCHECKBOXES(i)), COURSEID_in, TRAINDATE_in, HOURSTRAINED_in,
NEXTTRAINDATE_in, DATEADDED_in,
ADDEDBY_in, DATEMODIFIED_in, MODIFIEDBY_in, CURDEPT_in, CURDEPTDESC_in, mySeq);
END LOOP;
END;
