SQLPLUS How can I fix this procedure to make it work correctly?

Question

Alright. I copied this code from class, but I must have been half asleep at the time because it doesn't actually work.

Create or replace procedure display_row is
    (p_itemid IN item.itemid%TYPE) is
    v_itemid Number;
    v_itemdesc varchar2(30);
    v_category varchar2(30);
Begin
    Select *
    Into v_itemid, v_itemdesc, v_category
    From item
    Where itemid = p_itemid;
    Dbms_output.put_line(v_itemid || ' ' || v_itemdesc || ' ' || v_category);
End;

How can I fix this procedure so that it actually works?

Here's the user errors:

Remove the is operator from first sentence

Create or replace procedure display_row is 
                                        <--Here    

Your procedure should look like

Create or replace procedure display_row
    (p_itemid IN item.itemid%TYPE) is
    v_itemid Number;
    v_itemdesc varchar2(30);
    v_idemdesc varchar2(30);
Begin
    Select *
    Into v_itemid, v_itemdesc, v_category
    From item
    Where itemid = p_itemid;
    Dbms_output.put_line(v_itemid || ' ' || v_itemdesc || ' ' || v_category);
End;
