Data Import Question

I am working on importing a list of business data into my drupal site.

According to the developer (who provided this code), all I needed to do is to load my data into a temp table in the database which I have done.

From there, run this code and the data would be imported.

When I run this, I don't get any error, but nothing seems to have happened.

Any suggestions as to why?

function import_business() {
	$result = db_query("SELECT * FROM {aaaaa} LIMIT 0,10");
	while($item = db_fetch_object($result)) {
		//store information for each business in temp file
		$category = trim($item->category);
		$last_name = trim($item->last_name);
		$first_name = trim($item->first_name);
		$business = trim($item->business);
		$address1 = trim($item->address1);
		$address2 = trim($item->address2);
		$city = trim($item->city);
		$state = trim($item->state);
		$zip = trim($item->zip);		
		$phone = trim($item->phone);
		$phone = trim($item->phone);
		$phone = ereg_replace( '[^0-9]+', '', $phone );
		$phone = _convert_phone_to_array($phone);
		
		//insert data
		$node = (object)$node; 
    	        $node->type = 'business';  //required
    	        $node->uid = 1;  //required
    	        $node->name = administrator;  //required
    	        $node->taxonomy[1] = $category;
		$node->title = $business;
    	        $node->body = '';
    	        $node->street1 = $address1;
		$node->street2 = $address2;
		$node->firstname = $first_name;
	  	$node->lastname = $last_name;
		$node->city = $city;
		$node->state = $state;
		$node->zip = $zip;
		$node->phone1 = $phone;
		
		
		node_save($node);

	} 
}

According to him, the node_save will do everything that needs to be done.

Is this correct? Is there something that is missing?
