```As i stated i'm somewhat new to python myself so i defined the variables  in
a somewhat old fashion manner. The correct code is below. I also added some
comments because i think you defined the wrong variable somewhere also...
Because your code led to comprimento being compared to comprimento_aeronave
which was never defined anywhere, so i took it you ment comprimento_aeronave
there....

This code below is fully functional without any errors (not even identation
warnings ;-) ). So if this doesn't work at your computer something else is
possible wrong. Incidentally if you hit the following sequence : 1 2 3 4.
The program just terminates without a message... You'd have to insert what's
happening in such a case yourself.

**** insert code ****
global altura_aeronave, largura_aeronave, comprimento_aeronave, comprimento,
\
largura, altura

def compativel():
global altura, altura_aeronave, comprimento, comprimento_aeronave, \
largura, largura_aeronave
if not largura <= largura_aeronave:
print 'Volume largo demais!'
elif not altura <= altura_aeronave:
print 'Volume alto demais!'
elif not comprimento<=comprimento_aeronave:
print 'Volume comprido demais!'

def define():
global largura, altura, comprimento
largura=input()
altura=input()
comprimento=input()

def porao():
global altura_aeronave, largura_aeronave, comprimento_aeronave
porao = input()
if porao == 1 :
altura_aeronave = 111
largura_aeronave = 112
comprimento_aeronave = 211 #You originally had comprimento here?
return 1
elif porao == 4:
altura_aeronave = 112
largura_aeronave = 113
comprimento_aeronave = 212 #Same here
return 1
else:
print "Porao inexistente!"

if porao():
define()
compativel()

*** end inserted code ***
