thats what i have so far --

#!/usr/bin/python

import os.path

#open up the file
formisanoOpen = open("formisano_num.txt", "r")

#read in all the data into a list
readData = formisanoOpen.readLines()

#set up a sum
sum = 0;

#begin a loop
for trial in readData:

#the next line is indented (YA doesn't indent)
sum += int(trial)

#loop is over, so unindent
#report the sum
print sum


end

but it doesnt want to run for some reason....
