Hello,
I am new to multisim and I would like to ask for help because I am still learning how to make my own spice models. I am trying to import into multism a spice model of FDS4559 N channel mosfet. The source text of the model is given at the bottom of the post and it is downloaded from https://www.onsemi.com/PowerSolutions/supportDoc.do
I am trying to understand the mistake I made while importing. In the component wizard I did the following steps:
Can somebody please tell me where I went wrong? Thank you for your time. Source text:

Привет!
Для комплиментарных пар в Мультисим есть другие модели, а эта, похоже, для температурной, 4-выводной модели, для одного N-MOS
...-и моя попытка создать индивидуальный компонент тоже не привела к успеху, ошибка, думаю в неправильном назначении выводов, или вообще удалить лишний, - тогда на характериографе получим 2 кривые
А через SPICE-блок, вроде, всё правильно симулируется...
