Sounds like you have a bad query and instead of answer being a row,it's something else.
Print out everything before you use it:
instead of:$this->param = $this->SYSTEM->db->answer + $this->param;
$answer = $this->SYSTEM->db->answer;$param = $this->param;
echo "Answer: " . $answer . "<br/>";
If that's not an array, that's your problem and you'll have to debugwhy it's not an array.
