Help understanding how to pass dates to procedures in a package?

Question

When I run the following script in SQL*Plus, I get no obvious errors, but the truncate does not happen and all the other processing doesn't happen. I ran a similar version in another tool and it worked. Much of the code is deleted here but I believe I don't fully understand passing dates in the procedure. I figure if one of the dates ends up null or something invalid, the procedure will run and give no results. If someone could correct me on how to pass variables, it would help greatly. As you can see, I am passing 2 dates in from an ACCEPT statement, passing them to 1 shell type procedure which runs other procedures and passes the dates to the procedures below it. This procedures calls the 3rd procedure and passes the same dates to it:
ACCEPT CUR_PERIOD PROMPT 'Current Period (MM/DD/YYYY): ';
ACCEPT PRIOR_PERIOD PROMPT 'Prior Period (MM/DD/YYYY): ';
EXEC RCO.MONTH_END_PACK_1.MONTHENDPHASE1PROC('&CUR_PERIOD','&PRIOR_PERIOD');
The spec looks like this:
CREATE OR REPLACE PACKAGE MONTH_END_PACK_1 AS
     PROCEDURE MonthEndPhase1PROC(get_cur_period IN DATE, get_prior_period IN DATE);
     PROCEDURE W_CAT_INFO_RPT_PROC(GET_CUR_PERIOD IN DATE, GET_PRIOR_PERIOD IN DATE);
     PROCEDURE WO_CAT_INFO_RPT_PROC(GET_CUR_PERIOD IN DATE, GET_PRIOR_PERIOD IN DATE);
END MONTH_END_PACK_1;
The body looks like this:CREATE OR REPLACE PACKAGE BODY MONTH_END_PACK_1  AS
PROCEDURE MonthEndPhase1PROC(get_cur_period IN DATE, get_prior_period IN DATE) IS
     BEGIN
          EXECUTE IMMEDIATE 'TRUNCATE TABLE RPT_DS1_CNT';
          EXECUTE IMMEDIATE 'TRUNCATE TABLE RPT_DS1_CNT_CAT';
          W_CAT_INFO_RPT_PROC(GET_CUR_PERIOD, GET_PRIOR_PERIOD);
     END;
PROCEDURE W_CAT_INFO_RPT_PROC(GET_CUR_PERIOD IN DATE, GET_PRIOR_PERIOD IN DATE) IS
     CUR_PERIOD DATE;
     PRIOR_PERIOD DATE;
     BEGIN
          -- Assign the dates to this procedure that were passed in above.
          CUR_PERIOD := GET_CUR_PERIOD;         --07/27/2007
          PRIOR_PERIOD := GET_PRIOR_PERIOD;     --06/27/2007
          -- Execute stored procedure, passing in dates.
          WO_CAT_INFO_RPT_PROC(CUR_PERIOD, PRIOR_PERIOD);
          -- Other code goes here
     END; -- W_CAT_INFO_RPT_PROC
PROCEDURE WO_CAT_INFO_RPT_PROC(GET_CUR_PERIOD IN DATE, GET_PRIOR_PERIOD IN DATE) IS
     CUR_PERIOD DATE;
     PRIOR_PERIOD DATE;
     BEGIN
          CUR_PERIOD := GET_CUR_PERIOD;
          PRIOR_PERIOD := GET_PRIOR_PERIOD;
          INSERT INTO RPT_DS1_CNT
          (select distinct trim(CVBI_KEY) as CVBI_KEY, vendor_id
          from
          (select m.cvbi_key, v.vendor_name
          from  rco.cogs_resource m,RCO.COGS_SRVCTYP st,rco.cogs_mkt ms,RCO.COGS_VENDOR v,
            (select distinct cvbi_key, vendor_id
             from RCO.COGS_resource
             where period = CUR_PERIOD)ak
          where  ak.cvbi_key = m.cvbi_key
          and  trim(m.cvbi_key) = trim(st.cvbi_key(+))
          and  period = CUR_PERIOD));
     END;
END;

Answer 1

EXEC RCO.MONTH_END_PACK_1.MONTHENDPHASE1PROC(to_date('&CUR_PERIOD','MM/DD/YYYY'),to_date('&PRIOR_PERIOD','MM/DD/YYYY'));
As you can see, I am passing 2 dates in from an ACCEPT statementUntil you convert them using TO_DATE they are just strings
