Thanks for the advise gys, but I still can't decipher the problem.
Below is a copy of the entir progra, the erro is stil in the first
'if' command.

a = input ("Value for A? ")
b = input ("Value for B? ")
c = input ("Value for C? ")
d = input ("Value for D? ")
gen=0

print gen,a,b,c,d

while gen <=40 :
	
	gen=gen+1
	e= (b+d)/2+ (b-c)
	f= (a+c)/2+(b-d)
	g=(b+d)/2+(c-a)
	h=(a+c)/2+(d-b)

print gen,a,b,c,d
print gen,e,f,g,h	

	if e >= 1:
		a=e
	else :
		a=0

	if b>= 1 :
		b=f
	else:
		 b=0
	
	if g >= 1:
		c=g
	else:
		 c=0
	
	if h >= 1:
		d=h
	else:
		d=0

	i=a/(a+b+c+d)*100
	j=b/(a+b+c+d)*100
	k=c/(a+b+c+d)*100
	l=d/(a+b+c+d)*100
		
	a = i
	b = j
	c = k
	d = l
	
	print gen,a,b,c,d
