Before I download this, can you tell me what you mean by "they don't work"?
Do the animations not play properly? Do they play one time then no more? What exactly are they doing or not doing?
The most common problem people have with triggering animations, is that they trigger them every tick and the frame never goes past frame 1. I'm going to guess that this is the same problem that you are having.
It also may be better to make a new project with just one or two animations in it for people to check, rather than having your whole project there. If you have the problem in your project, it will be the same in a new project if you build it the same way.
