ORA-06550 with stored procedure

Question

Any ideas on this error?
Tried to create procedure first:
SQL> start c:\cs603\enter_website.sql
Warning: Procedure created with compilation errors.
Then with exec I get this:
SQL> exec enter_website('u1','p1');
BEGIN enter_website('u1','p1'); END;
ERROR at line 1:
ORA-06550: line 1, column 7:
PLS-00905: object TEST.ENTER_WEBSITE is invalid
ORA-06550: line 1, column 7:
PL/SQL: Statement ignored
Here is the procedure code:
create or replace procedure enter_website(u, in users uname%type, p in users.pname%type) as
set serveroutput on size 1000000 format wrap
declare
     usercount, pagecount number;
begin
     select COUNT(*) into pagecount
from pages where p = pname;
     if pagecount = 1 then
          select COUNT(*) into usercount
from users where u = uname;
          if usercount = 0 then
               insert into users values (u, p, ‘a’, 1);     
          else
update users set status = ‘a’ where u = uname and p = pname
          end-if
     else
          dbms_ouput.put_line(‘Page does not exist.’);
     end-if
end;
Any thoughts?

    end if;
  else
    dbms_output.put_line('Page does not exist.');
  end if;
end;
getting error:

It is not liking PNAME for some reason.
