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
