Hey Chris, thank you for your help! Your last comment with the (!!)-thing was a very good idea! Now my function looks like this: tmp:: [(Int, Int)] -> Int -> (Int, Int) tmp [] y = (0,0) tmp xs y = xs !! (y-1) If the function returns (0,0) it will blocked by another function. If I want to use the "maybe" return, I get some new trouble that I don't like - so I chose that way :) Thank you again Kevin
