I am trying to get a program to add up input from the user to get to
the number 100 using a loop.  However, I am having some issues.  Here
is what I have so far.  I know I am just trying to hard, but I am
stuck.  Thank you for any help.

print "We need to count to 100"

high_number = 100
total = 0

number = input("Enter your first number ")
sum = number + total
while sum < high_number:
    print "Not there yet..."
    number = input("Enter another number ")

print "We are there!!!"
