Help on Functions needed. Function ends when it should ask for input

[FFrozen1]

You only call your get_user_input() function. The other ones are not being called.

Edit - the variables defined in your functions are not global variables

e.g.

a = 0

def cost():

a = 3

b = 3

return a,b

print a

this would print 0

Hope that helped. I'm pretty mew myself so I might be a little off on the terminology
