here is the code:

while option != 5:
if option == 1:
newExpence = addExpence(totalBudget)

printOptions()
option = input("What would you like to do? ")
elif option == 2:
removeExpence = removeExpence(totalBudget)
totalBudget = totalBudget + removedExpence
printOptions()
option = input("What would you like to do? ")
elif option == 3:
newRevenue(totalBudget)
printOptions()
option = input("What would you like to do? ")

main()if i choose option 1 the program runs as expected, but with option 2 i get the following error:
Traceback (most recent call last):
File "C:\Python25\personalBudget.py", line 68, in <module>
main()
File "C:\Python25\personalBudget.py", line 12, in main
removeExpence = removeExpence(totalBudget)
UnboundLocalError: local variable 'removeExpence' referenced before assignment
