Geosets merging problem

[Amaruak]

Well, I tried to attach knight's head to foot's body, as in this tutorial http://www.oinkerwinkle.com/tools/tutorialheadswitch2.html but for some unkown reasons, head doesnt show up I tried to make this as acted in tutorial, step by step about 3 times... but effect is still the same. Seems like geoset head is added correctly, but it doesnt show in game and in wc3viewer. I attach this model, pls check whats wrong someone...

I have just found problem. To convert .mdl to .mdx I used MdlVis (just opened .mdl and saved as .mdx) and that was fault. When I use War3FileConverter it works fine. Thanks for trying help (those 6 people who viewed attached model )
