mysql use group by column in where condition

Question

How can I make this query work :

SELECT column1.....,SUM(Hits) AS Hits   
FROM table 
WHERE  SUM(Hits) > 100
GROUP BY column1.....

The problem is the where clause, mysql display error :

Error Code : 1111
Invalid use of group function

I try to change the query to :

 SELECT column1.....,SUM(Hits) AS Hits   
    FROM table 
    WHERE  Hits > 100
    GROUP BY column1.....

It did not help.

thanks
