[Zope] urllib.urlopen

I'm trying to grab a data file using urllib.urlopen with this code: def powerData(self,REQUEST): import csv import urllib inFile = urllib.urlopen('http://www.davisenergy.com/zeh_data/A042304.DAT') return inFile but I get the error: global name 'inFile' is not defined I've also tried some variations on this: inFile = "".join(urllib.urlopen('http://www.davisenergy.com/zeh_data/ A042304.DAT').readlines()) Ideas on what's not working? thanks -- David
