Hi all,

I'm sure I'm doing something wrong but after lots of searching and

reading I can't work it out and was wondering if anybody can help?

I've got the following block of code:

if a >= 20 and a < 100:

if c == "c":

radius = 500

else:

radius = 250

elif (a >= 100) and (a < 500):

radius = 500

elif (a >= 500) and (a < 1000):

radius = 1000

elif (a >= 1000) and (a < 3000):

radius = 1500

elif (a >= 3000) and (a < 5000):

radius = 2000

else:

radius = 4000

No matter what value goes in for 'a' the radius always comes out as

4000.

What am I doing wrong?

Cheers

Neil
