Help with learning custom spells through triggers...

I am working on my new Ogre Campaign, and I've made custom skills with it, but now, with my map, I want to make it so that right at the very start of the first level, one of your skill points is spent right at the start, through triggers. There's only one problem. I set the Action to "Hero - Learn Skill", then I try to make him learn the skill, but it doesn't show up in the menu. Is there any possible way to make my hero learn custom skills through triggers like this, or am I stuck?

the only way i can think of doing this is setting that abbility into an arrey variable and say learn abillity varriable ( i dont know if this is possible though)

In the menu, pick the skill that the custom ability is based on. Even though it's not the same ability, it'll work.

use unit - add abillity :D
