hi again... :) Ok assume i got this list of tuples [(10,1),(20,2),(30,3)] where i in (i,j) is a index, i want to go through the list and add a number witch matches the best index. Like 18 should give me [(10,1),(20,3),(30,3)] since 18 are over 10 and under 20... aky? something like [if (thenumber < index) then (index,int+1) \and break\ else (index,int) | (index,int) <- [thelist]] My problem is that i dont know how to do the break thing! next time the value gonna be smaller than the 30 and ++ the int. Can i use some help-boolean to set it false when we have counted up once? and include that one in the if-stmt?? How do i do that? I guess your laughing your pants wet right now coz there are of-corz some smart built-in functions in haskell to do this kind of silly ting, so please tell me! :) Respect the rock! //Fredde
