Stored pl sql question

Question

Hello, I'm trying to select maximum number of employee in a department using this function:
create or replace function MAXEMPS (maxemp IN varchar2)
return number IS max_p varchar2
begin
select dept.dname, count(*) into max_p from dept join emp where dname=maxemp
on dept.dname = emp.dname
group by dept.dname
having count(*) = (select max(count(*)) from emp group by emp.dname);
return max_p;
end MAXEMPS;
by the way this is the table:
create table dept
DName varchar2(25),
CityLocated number(5),
constraint dept_pk primary key(DName)
create table EMP
EID number(7),
EName varchar2(25),
DName varchar(25),
constraint EMP_pk primary key(EID),
constraint EMP_fk foreign key references DEPT(DName)
unfortunately my function got an error and I have no luck to fix this function
thanks for the help :)

Answer 1

my bad I really should use 'show errors' from the begining...
create or replace function MAXEMPS (max_p dept.dname%TYPE;)
return number IS max_p varchar2
begin
select dept.dname, count(*) into max_p from dept join emp where dname=maxemp
on dept.dname = emp.dname
group by dept.dname
having count(*) = (select max(count(*)) from emp group by emp.dname);
return max_p;
end MAXEMPS;
*based on the above code I've got these error messages:
LINE/COL ERROR
