Access node attributes from the API

Okay, I have created a custom node using CCK called "business". I am trying to create a block which will display the businesses and their testimonials. Here is the code I am trying to use:

<?php

$sql = "select * from {node} where type = 'content_business'";
$result = db_query(db_rewrite_sql($sql));

while ( $data = db_fetch_object($result)) {

  $node = node_load($data->nid);

  print $node->title."<br>\n";
  print $node->field_testimonial."<br>\n";

}

?>

The title displays fine, but the testimonial only displays "Array". "field_testimonial" is the name shown in the "manage fields" section, but I must be missing something.

What gives?
