queryByAttributes returns 0 every time

[Ryan Ollerenshaw]

I cant seem to get queryByAttributes to work correctly, I always get 0
results every time, here is the php code that i am using:

$queryString = "(TEAM_ID > 1)";
$mroLayer->queryByAttributes('TEAM_ID',$queryString, MS_SINGLE);
echo "RESULTS: ".$mroLayer->getNumResults()

I have also tried:
$queryString = "(TEAM_ID > '1')";
$queryString = "('TEAM_ID' > '1')";
$queryString = "('[TEAM_ID]' > 1)";

Nothing seems to work, I am using php 5.4.1 and mapserver 4.10.1
