Several of my messages via gmane seem to be bouncing so
I'm sending this direct to the tutor list.
Apologies if it arrives twice!

Unfortunately this is a text based mailing list so your
attachment has been removed by the server. We can't see
your code. However we do see the error message this
time so we can make a guess...

It says 'i' is not defined.
I suspect you have used i as the parameter name in
your methods as suggested in the assignment.
Then you have tried to call the method and also
passed an 'i' in when making the call (as shown
in the error message). But the i in the method
definition is only visible inside the method code.
You must define the value you pass in. Something like:
my_inbox = SMS_store()
i = 1 # define a value for i
print( my_inbox.get_message(i) ) # use your local i
# now use the method to print all messages
for msg_number in range(my_inbox.message_count()):
print( my_inbox.get_message(msg_number) )
