I'm trying to get this function to work but for some reason it errors out on the foreach line saying there is an invalid argument.
$scores= TESTAPI::GUL($user->ID);
if (empty($scores)) {
echo "<p>No Scores</p>";
} else {
foreach ($scores as $score) {
echo "<p>".$score."</p>";
}
}
The error I get is: PHP Warning: Invalid argument supplied for foreach()
