[Trigger] Aquiring abilities through spellbook

[_North]

I'm trying to have a hero have a spell book as one of his abilities, in the spellbook are a set of abilities that when pressed, remove the spell book and replace it with the chosen abilities
this is my trigger:

• Untitled Trigger 001
  • Events
    • Unit - A unit Begins casting an ability
  • Conditions
  • Actions
    • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
      • If - Conditions
        • (Ability being cast) Equal to Shotgun Slugs (Dummy)
      • Then - Actions
        • Unit - Remove Invulnerable buff from (Triggering unit)
        • Unit - Add Shotgun Slugs to (Triggering unit)
        • Unit - Set level of Shotgun Slugs for (Triggering unit) to 1
        • Unit - Remove Gun Enchancements from (Triggering unit)
      • Else - Actions
        • Do nothing

The result is that the selected ability appears and the spellbook dissapears, however, in the Hero Abilities windows, the spell book remains and the selected ability is not. What would be the solution?

I think the abilities adding applies only to the abilities stated in the object editor.
But I have an idea that could help!
1. If we're talking about an ability that doesn't have to be MUI you could add this action to your posted trigger:

• Set ability = Shotgun Slugs

If not, we're talking hashtables:

• Hashtable - Save Shotgun Slugs as 0 of Key(Triggering Unit) in hashtable

2. We're going to make a trigger that adds a level to the ability instead of adding to the spellbook, so that after casting the dummy ability when the hero upgrades his spellbook ability what he will ACTUALLY do is upgrade the Shotgun Slugs:

• Add to Ability
  • Events
    • Unit - A unit learns an ability
    • OR
    • Unit - A unit adds to an ability
  • Conditions
    • Ability equal to Spellbook
  • Actions
    • Unit - Remove Spellbook from (Triggering Unit)
    • Unit - Set level of ability for (Triggering Unit) to ((Level of ability for (Triggering Unit)) + 1)

Idodik's idea should be the answer, but anyway, just to remind to all of you people, DON'T USE

• Do nothing
