pl/sql procedure help--getting error

guys i have the following cust search procedure, but it failed while compiling
any help would be appreciated. This procedure takes zipcode as input
parameter & displays zip, cust name, & total sales for each cusomer;
************
create or replace procedure zipCust
(v_zip IN Customer.zip%type
v_zip OUT customer.zip%type;
v_name OUT Customer.name%type;
v_sum OUT Ord.Total%type;
)
as
cursor cur_cust (v_in_cur INcustomer.zip%type) is
select zip, name, sum(total) INTO
v_zip, v_name, v_sum
FROM customer c, Ord o
where c.custid =o.custid;
group by zip, name;
begin
open cur_cust (v_zip);
loop
fetch cur_cust into v_zip, v_name, v_sum;
exit when cur_cust%notfound;
dbms_output.put_line ( ' customers in:'|| v_zip || v_name || v_sum );
end loop;

end;

cursor cur_cust (v_in_cur INcustomer.zip%type) is
select zip, name, sum(total) INTO
v_zip, v_name, v_sum
FROM customer c, Ord o
where c.custid =o.custid;
group by zip, name;

In this code
do not use into clause

Instead,use following code for cursor:

cursor cur_cust (v_in_cur INcustomer.zip%type) is
select zip, name, sum(total)
FROM customer c, Ord o
where c.custid =o.custid;
group by zip, name;
