stored procedure not working

[Matt Dinatale]

Im new to stored procedures and i don't know why this doesn't work

CREATE PROCEDURE `sp_clk4`(id INT)
BEGIN
DECLARE nc INT;
Select numclk INTO nc from videos where vid = id;
SET nc = nc + 1;
UPDATE Videos SET numclk = nc where vid = id;
END


I want to take the result from on select statment and add one to it then use it to update the table. Thanks for your help
