no, I'm not using list:

my program has two functions:
gammad(k,t,n) and gammad_cdf(k,t,n)
from the second I want recall the first to make an integral, using u as "du".
With my code I get "bad argument: ex. using gammad_cdf(7.5,1,8) the program gives "int(gammad(7.5,1,0),0,0,8) error..." (it sees u=0 but (int(gammad(7.5,1,8),u,0,8) is ok)...
