Wrong with this script?

For future notice, it's useful to

(1) explain what it is you want your script to do, and
(2) explain what it currently does (including an exception traceback if 
one is printed)

Using my mind-reading powers, I'd suggest that maybe you want something 
like:

py> for limit in iter(lambda: raw_input('What number? '), ''):
...     if limit == "help":
...         print "The Fibonacci series..."
...     else:
...         a, b = 0, 1
...         limit = int(limit)
...         while b < limit:
...             print b
...             a, b = b, a+b
...
[... I type '6' ...]

[... I type '13' ...]

[... I type '' (nothing) ...]
