Error in my application.

[troopers]

Hey all I have an error in my Facebook application and I'm not sure what's wrong (New to PHP).

 

The error output is:

 

Warning: array_rand() [function.array-rand]: Second argument has to be between 1 and the number of elements in the array in /home/app/view.php on line 15

 

And the PHP lines are as follows:

 

	$friends = $facebook->api('/me/friends');
                print_r(array_rand($friends, 3)); 

[upp]

what does $facebook->api('/me/friends') return?

It returns 3 random friends from the users friends list and displays them on the page.
