You should tell what exactly your problem is ;)
But why so complicated? I would do the following construct:

---/---
>>> sum= 0
>>> sum_stop= 100
>>> while sum < 100:
...   num= input("Please enter the number: ")
...   sum= sum+num
...   print ("The sum is now "), sum
...   print "The sum is >/= 100!"
---/---

What is different here is, instead of the for-loop i use a while loop,
which seems more appropriate to me, because the programm should go
through the loop _until_ 100 is reached.

There are some other things that are a bit strange in your code. Maybe
you write a mail and explain what you wanted to do in each line.

Bye
Marco
