PL/SQL Output problem

Hi all,

First of all, thank you for taking time to read my posting. I have written a small procedure to help me locate a department name and it's address, and i would like to print these information onto the screen in a nice format. Example:
Department: xxxxx
Manager: aaaaa, bbbbbb

my codes are something like this:
.....

  dbms_output.enable;
  dbms_output.put_line('Department: ' || deptname);
  dbms_output.put_line('Manager: ' ||  mgrlname || ', ' || mgrfname);

my procedure complie successfully without any errors, however when i try to execute my procedure i got these runtime error saying:

21/3     PLS-00306: wrong number or types of arguments in call to


         'PUT_LINE'



21/3     PL/SQL: Statement ignored
22/3     PLS-00306: wrong number or types of arguments in call to


         'PUT_LINE'



22/3     PL/SQL: Statement ignored

I don't quite understand what these errors means. All my variables (deptname, mgrfname, mgrlname) are of type varchar2(20). Where did i go wrong? I really appreaciate your help very much. Thanks in advance!
