Howdy!
I just took a look at the model and it's basically fubar, it doesn't look like your first attempt at making the model worked out well - but don't be discouraged, it takes time.
My advice is to do the following:
1. Always have a Good working model open in a copy of Nifskope so that you can see how the higherarchy is supposed to be.
2. I would try again at making a model, but use a very simple one this time - its better to master the process using Beer bottles, Ashtrays and Boxes before you get into the complex stuff.
3. Work through the process very slowly, making sure that at each step you copy/paste into the exact right order within the NIF file. You will definitely make mistakes and have to start over before you get it right. If you keep at it, you will eventually produce a NIF that has the exact same look in Nifskope as the Ashtray - and it is That one which will work.
Now with that said, here are some specific things I saw with the model:
A. You have BSSShaderPPLightingProperty at the root level, same as BSFadeNode - this cannot be, the BSFadeNode must always be the top-most level or root. If you paste anything and it shows up at the root level, right-click it and choose "Block" then "Remove Branch" to clear it out so you can try again.
B. When you have multiple NiTriStrips, they all need to be at the same level as one-another. If they don't, the order is wrong and you'll need to delete and try again.
C. Your bhkCollisionObject is also not looking right, you'll need to work this process step-by-step again.
The important thing to remember is that the screenshots in the tutorial show the exact higherarchy, which your models will need to imitate to work. Take your time, once you get it right once it will get Alot easier and you'll actually start to have fun. Once you master making models with single NiTriStrips (like Ashtrays), you can start working on models with multiple tri-strips.
Lastly, I highly recommend that you download Artisten's Video Tutorial (link is in the Tutorial), as it walks you through the Exact process (just without audio). This is critical because you see where the mouse clicks go, and when to do what.
Try a few more and send me links, I'll check em out.
Luck!
