Well, you're not returning the total from your function

Code:

public function count_hygiene_factor($name)
{
  //query to sum up the scores
  //Need to provide an alias for your total in order to retrieve it from the result
  $sql = "SELECT SUM(Factor2Score + Factor5Score + Factor6Score + Factor8Score + Factor9Score + Factor12Score) AS `total`
      from FactorSurveyScore
      where Name = ?";
  
  //2nd parameter for bindings should be an array of data in order that they appear in the query.
  $q = $this->db->query($sql, array($name))->row();

  if ($q->num_rows() > 0)  //check for result
  {
    return $q->total;  //actually return the value
  }
  else
  {
    return 0;
  }
}
