MySQL MAX(), AVG(), and MIN() not working in PHP

Hey,

Whenever I run this script something is going wrong because the max(), avg(), and min() values are coming up as 0. I have run is_null() on all of them and they are not NULL. They are just coming up as 0, but they shouldn't be. 1 vote has been "4" and 1 vote has been "2" so I should be coming up with an avg of 3, max of 4 and min of 2. I can only get COUNT() to work in the statement below, which is giving me the correct answer of 2.

Thanks. Any help is appreciated.
$get_advice_sql = "SELECT a.ID, a.person_ID, a.type, a.keywords, a.title, a.information, a.effect_start, Count(v.vote), Avg(v.vote), Max(v.vote), Min(v.vote), u.clsUserName
				FROM articles as a 
				LEFT JOIN USERTABLE as u ON u.clsUserID = a.person_id
				LEFT JOIN votes as v ON a.ID = v.article_ID
				WHERE a.type = 'advice'
				AND a.ID = (SELECT max(ID) 
							FROM articles
							WHERE type = 'advice')
				GROUP BY a.ID";
	if ($result = mysqli_query($mysqli, $get_advice_sql)) {
		while ($row = mysqli_fetch_row($result)) {
				$advice_id = $row[0];
				$title = $row[4];
				$information = $row[5];
				$effect_start = $row[6];
				$votes_count = $row[7];
				$votes_average = $row[8];
				$votes_max = $row[9];
				$votes_min = $row[10];
				$author = $row[11];		
		}
	}

Sorry, I posted this question and realized that it was actually a problem while I was putting the initial data into MySQL. I was putting in the votes as 0's so of course it was coming up with 0 for the max, min, and average!

Feeling like an idiot :/

Sorry guys
