just explain what you are doing in some sort of detail.
Saying what you trying to do and that all you see are floating shoulders tells me only you are doing something wrong or missed something. I cannot tell you what because you haven't said what you have done to go from point A to point B. You can't expect modders to be either psychic or spend ages randomly guessing.
an easy way to receive help would be upload the nif you have modified to a file sharing website, rapidshare/megaupload/whatever. Then, maybe, someone will look at and just tell what to do to get it working correctly.
Alright, I think this link should work? http://rapidshare.com/files/437843593/StormWalker.nif Sorry I've been so unhelpful :\ but thanks for telling me how I can do all this

if that link doesn't work then basically all I've done is copy and paste the shoulders of the Tesla armour on to the Ranger combat amour and I've also copy & pasted the electricity effect...
