combining unix stderr output with stdout

The problem is that when I run script x and redirect it to a file, all of the error messages come to the screen when I want them to also go to that file. 
 With bash shell, use: 
 program > outputfile 2>&1 
 My colleague found this for me in the book Unix Power Tools which is available online at UCLA here. http://proquest.safaribooksonline.com/0596003307
