Learn Spells on item manipulation

What im trying to do in my map: Create a system where a hero will have items in their inventory so they can learn spells upon manipulation of an item (Basically several heroes in one)
Problem: When my hero manipulates the item the spells are not learned
Curren trigger

Event
Unit - A unit uses an item
Condition (Item-type of (Item being manipulated)) Equal to Ice Magic Level 1
Then
Hero - Learn skill for (Hero manipulationg item): Blast of Ice Level 1
^^^Repeat for other skills
Hero - Create Ice Magic Level 1 and give to (Hero Manipulating Item)

I have the items that are manipulated as charged

This might be your problem, when you learn a skill you need a hero level. You should do Unit - Add Ability instead.
