[Tutor] Globals?

Hi all, 

Having trouble with something, it is 3:30am in the morning, so this
may be a dumb problem, if so, I apologise.

In my prog, there's two variables created right at the get go -

import imaplib
import email.Parser
import os
import os.path
import datetime
import md5
from pause import *


as I want them to be global within this module, so that another module
can pick them out easily.

Now, I just added badConnectCycle, badUserList has been there awhile,
and it's used in

the function connectToImap which is called by getReturns which is
called by main(), and my other module can get it no problem, so
badUserList is fine.

badConnectCycle... is giving me errors -

badConnectCycle is used in getReturns, as so - 

if session == "NoConnect" : 
            badConnectCycle += 1

function getReturns ends as follows - 

if badConnectCycle == len(user) and badConnectCycle > 0: return ("NoConnect","")
if badUserList and not sender: return ('NoLogin',"")
if matchindex[0] and not sender: return ('NoNew', '')
if not sender: return ("NoMatch","")
return (sender, msgdata)

and it's at that line

 if badConnectCycle == len(user) and badConnectCycle > 0:

that I get this error:

UnboundLocalError: local variable 'badConnectCycle' referenced before

Which is confusing me because badUserList is used within a function
called by getReturns, and I've had no problem with it.

Help anyone? Much appreciated if you can.
