有关存储过程的问题

内容如下:
CREATE PROCEDURE SP_AVG  
            @COUNT INT OUTPUT,
            @WRITTEN_SCORE INT = 60,
            @LAB_SCORE INT = 60
    AS
    IF(NOT @WRITTEN_SCORE BETWEEN 0 AND 100 OR NOT @LAB_SCORE BETWEEN 0 AND 100)
    BEGIN
    RAISERROR('及格线错误，请指定1-100之间的分数，系统中断退出')
    RETURN    
    END
    DECLARE
        @WRITTEN_SCORE_AVG FLOAT,
        @LAB_SCORE_AVG     FLOAT
    SELECT
        @WRITTEN_SCORE_AVG = AVG(I_EXAM_WRITTEN_SCORE),
        @LAB_SCORE_AVG = AVG(I_EXAM_LAB_SCORE)
    FROM
        TAB_EXAM_INFO
        
        PRINT '笔试平均分:'+CONVERT(VARCHAR(5),@WRITTEN_SCORE_AVG)
        PRINT '机试平均分:'+CONVERT(VARCHAR(5),@LAB_SCORE_AVG)
    IF(@WRITTEN_SCORE_AVG > 70 AND @LAB_SCORE_AVG > 70)
                
    PRINT '本次考试成绩:优秀'
    ELSE
    PRINT '本次考试成绩:较差'

请问他报错问题是
消息 102，级别 15，状态 1，过程 SP_AVG，第 8 行
')' 附近有语法错误。

请问怎么错了阿 有高手解答下么
