"Learning a spell costs money" problem.

[Manix]

Alright, my trigger is supposed to trigger when a unit learns a spell and it's supposed to check if player has X gold, if not level of ability is set to -1, the problem is that I can't find the right condition to check if the player has the gold, what I got is this:

LEARN SPELLS
    Events
        Unit - A unit Learns a skill
    Conditions
    Actions
        If (All Conditions are True) then do (Then Actions) else do (Else Actions)
            If - Conditions
                ((Owner of (Triggering unit)) Current gold) Less than (50 + [B][COLOR="Red"]((Level of Acid Bomb for (Triggering unit))[/COLOR][/B] x 50))
            Then - Actions
            Else - Actions

The problem part is bolded and red, the problem is that there is no "learned skill", only "ability being cast" .. What should I do :?

I need to get "Learned Skill" in the integer arithmetic ... How do I do that ?
