[Tutor] Problem with while loop

[matte]

Hi guys

Please excuse me but I've been out of Python for a while since my laptop was
stolen...

I'm battling with a very basic while loop....

-------------- 8< ----------------------
#!/usr/bin/python

from random import randint

counter = 0

howmany = raw_input( "How many: " )

while counter < howmany:

    pin = randint(0000,9999)
    print pin
    counter += 1

-------------- 8< ----------------------

For some reason if I use an integer in place of "howmany" it works, but I'd
like it to work as I can logically see it above.

What am I missing ?
