Adding the files into the map

I made some custom spells and now the tutorial sais to add the extracted files into the map... I did... and then i loaded my map but it doesnt appear in the list of abilities when you modify a unit's abilities.... WHERE IS IT?

HELP ME!! :...:

add a directory called 'units' in your wc3 folder, and put the files (abilitydata.slk, *func.txt, *strings.txt) into it. when you load up WE, it will look there for your abilities. when you want to PLAY the map, then insert those same files, into the map. otherwise other people wont be able to play the map. when you open the map with ME, it will wipe those files out, and if you save it, youll have to insert the files again.
