'Check Yourself' error


Can anyone explain to me why the following code gives me an error?
I have no idea what I'm doing wrong.

print 'Welcome to the Pig Latin Translator!'

raw_input("Enter a word:")
original = raw_input

if len(original) > 0:
    print original
    print "empty"


Change it so original = raw_input("enter a word: ")

Hope this helps!
