Trouble making new unit abilities function

I've figured out most of it on my own, but I sometimes have trouble adding certain special abilities to units. The button for the unit's ability is there, but when I click it, I hear a short tone that indicates it's unavailable and nothing happens. The three cases I'm unable to solve are adding the Concentrate Fire ability to a certain starfighter, adding the Proximity Mine ability to Rebel Plex soldiers, and adding the Stimpack ability to Rebel soldiers.

I've looked pretty thoroughly to make sure they should work based on what the code for other unit abilities looks like, but I'm stumped on these three.

Got any code I can have a look at to see if i can help.

Paste the stuff on Unit Abilities for the xml file your trying to create.

This is for the TIE/fc, I have these abilities under both the individual fighter and the squadron.

Right ok, i've had a look over your code and i cannot see anything wrong with it. Do the units appear in game with the ability on them?

Could you send me an attached ZIP with all the related xml files?

Sure, but remember, I can't really release this stuff as content for other people to use, because it's a mixing of other mods along with my own stuff, for my own personal use. But just for the sake of helping me out I guess it's okay, should I email it?
