hello @Kulkul thanks a lot i really appreciate . thank you soo much. it works just if started with sections but i want to read from the created sections directly and no need to selct the desired sections. but just to confirm the input to list chop must be from type ?? because i tried to use the the output from list transpose (elements as in the fourth snap shot) as an input to list chop but it didn’t work ?? ---
