If the result will be only one, you can use 'row_array' instead of 'result_array'. If you use row array you can access the value by $r['amount'] If it is result array you can access the value by $r[0]['amount']

Your error message is saying Message: Trying to get property of non-object. You also calling $data['r']=$query->result_array(); So it is not an object, It is an associative array. As it is not an object rather than it is a associative array so you can not use -> Operator. You need to access value like $r['amount'].

You also can value check in your template file. like this <?php echo isset($r) ? $r['amount'] : ''; ?>

You can also var_dump before printing in the template.

I think it will help you. Thank you.
