You have 2 errors there:
#1
In "Configuration" trigger change this line:
-
Set EF_Ability = Energy Field (Dummy)
into this line instead:
-
Set EF_Ability = Energy Field
At the moment your trigger won't even fire, because it checks incorrect spell (it checks if ability cast is dummy spell instead of the spell your hero uses)
#2
You have incorrectly set your dummy unit's model file. You can fix that in two ways:
a) Go to Import Manager and change the Full Path of your dummy.mdx model to "dummy.mdx" instead of "war3imported/dummy.mdx" that you have there right now
b) Go to Object Editor, find your dummy unit and change its Art - Model File to that of the imported model (e.g. to "war3imported/dummy.mdl")
Do it one way or the other, but don't do both ways, else you will end up in the same situation as right now.
The problem here is that the imported model is "war3imported/dummy.mdx" while you set the Art - Model File as "dummy.mdl" only - this causes the dummy unit to have no model at all and so there would be no visual effects.
If you take a look in the Energy Field map's Import Manager, you can see that the dummy model has path set to simply "dummy.mdx"
