Example plant id 127 has >30 and <30 Only <30 shows up. Is doing size IN values (1,2) in sql

Example of field criteria to get to work:

        if ($this->size) {
            foreach ($this->size as $value) {
                $criteria2->compare('size',$value,true,'OR');
            }
            $criteria->mergeWith($criteria2); //defaults to AND
        }
