Problem with loops in Mathematica


Hi all, 

I am trying to work out the value of S at different nodes in a
binomial tree, using the following formula: 

Table[S u^j d^(n - j) p^j q^(n - j), {j, 0, n}] 

I would like to loop this in some way so that I don't have to assign
new values to n all the time (S, d, p, q are given). I have tried For
and Do, but when i print the result, Mathematica produces n lists that
are equal to the final value of n, and not for n=0,1,..., n-1. 

Anyone who could help me with this?
