How to import spells?

Hey.
I try and I try over and over again to import spells but it just doesn't seem to work out for me. Can you explain how to do it on a "dummy" level, please? Thanks in advance!

before importing spells, first import the buffs, then spells, then units (and dummies) and then the trigger as last (in this way so everything recognnizes eachother)
