Greetings kobsx4,
>Hello all, I have been struggling with this code for 3 hours now

> score = input('Enter their score: ')
> totalScores = totalScores + score

> print "Your score must be between 0 and 100."
> score = input('Enter their score: ')

> return totalScores
>------------------------------------------------------------------------------
>the program is supposed to find the average of two test scores and

Suggestion #1:
--------------
When you are stuck on a small piece of code, set it aside (stop
looking at it) and start over again; sometimes rewriting with
different variable names and a clean slate helps to highlight the
problem.
Professional programmers will tell you that they are quite
accustomed to 'throwing away' code. Don't be afraid to do it.
(While you are still learning, you might want to keep the old chunk
of code around to examine so that you can maybe figure out what you
did wrong.)
Suggestion #2:
--------------
Put a print statement or two in the loop, so that you see how your
variables are changing. For example, just before your 'while' line,
maybe something like:
print "score=%d totalScores=%d" % (score, totalScores,)
Suggestion #3:
--------------
Break the problem down even smaller (Rustom Mody appears to have
beat me to the punch on that suggestion, so I'll just point to his
email.)
Hint #1:
--------
What is the value of your variable totalScores each time through the
loop? Does it ever get reset?
Good luck with your degubbing!
