Stored Procedure

I need to update this Stored Procedure by adding a row. Please Advise

 I have another table called the Item's Table with Item_ID, Item_description, Item_Price.  I need to create a stored procedure that will add additional item row?  I attempted to creat the procedure and received number error messages

Here is what I created:   When I execute I receive error message: Msg 102, Level 15, State 1, Procedure ADD_ITEM, Line 4 Incorrect syntax near 'NUMERIC'.  

What am  I doing wrong?   Thanks


CREATE PROCEDURE ADD_ITEM  -- Create a new item      
   @item_id_arg NUMERIC,         -- This parameter is the new item ID.
   @item_description_arg VARCHAR(30), -- This parameter is the item description.
   @item_price NUMERIC  -- This parameter is the item price.
   
   AS -- This "AS" is required by the syntax of stored procedures.
BEGIN
  -- Insert the new customer with the parameters given, and a 0 balance.
  INSERT INTO item (item_ID,item_description, item_price)
  VALUES(@item_id_arg,@item_description_arg,@item_price_arg,0);
END;

I changed the arugment '@item_price NUMERIC' to '@item_price_arg NUMERIC' and remove the 0 on the INSERT statement.

I am still receiving INcorrect syntax error.
