Problems with if/elif statement syntax

[Neil Webster]

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
