messed up RE....i think

[Patrick C]

So I'm trying to just write a script that checks to see the national debt every minute for 3 minutes. (the time and duration is completely variable, im making up these tests for me to learn on)...

So the script I have, which I've written by cutting and pasting from previous questions i've had answered and from what i've found on python.org, yields "None," rather than 3 gigantic debt figures.

Can someone help me (i'm using Windows XP on python 2.5) find where I've gone arwy...
thanks a lot...

first look, you did not return any values in your debtcheck() function that's why you have None.. return debt_data in that function, and i think it should be fine.
