without seeing code its really difficult to come up with an answer

[brack]

the code is very simple...
but where is the mistake...notice that it is my first code in haskell...!

comb :: Int -> Int -> Int
comb n 0 = 1
comb n m = comb(n-1) (m-1)  *  n 'div' m

thanks...

you need to use `` instead of '' (it is kind of hard to see the difference but hopefully you should be able to spot it)

now, how can i run it? i did a :load lab1.hs.
it appeared main> and i tried to put eg.

5 6 <enter>

comb 5 6
