Decrease mana of units [Object Editor Ability problem]

[CoLd Bon3]

Hello there, guys! I tried to make a system for my map that keeps a unit's max mana the same amount, despite everything.
So, for example, i have a unit and i want it's max mana to be 150 at all the times. And when the hero gains a level or loses/gains an item, i run a trigger that stores the units current max mana - 150 in a variable (the mana that should be removed).
I also have 4 skills. The first one sets the mana to be -1 at level 2, -2 at level 3... -9 at level 10. The first level removes 0 mana. The second one sets the mana to -10,-20...-90, the third one to -100,-200...-900, the fourth one to -1000, -2000... -9000. All the four skills have the first level removing 0 mana.
And, i convert the variable that stores the mana that should be removed to a string variable.

Let's say the mana that has to be removed is 825 - 150 = 675. I should set the first skill to be level 6 (-5), the second skill to be level 8 (-70), the third one to be level 7 (-600) and the fourth one to be level 1 (-0). You get what i want to do? At the end, the mana will be reduced by (-600) + (-70) + (-5) = -675.
To be sure that i get the right values, i make the game display those values as a game message. When the mana needs to be reduced by 675 i get this :
6
8
7
1
(i add +1 because as i stated before - level 1 reduces no mana)

And, my algorithm is right, i get the right values, but the levels don't get changed. I first tried by making them Item abilities, then Unit abilities, then Hero abilities. Nothing happened. I even tried to give the abilities to the unit trough the object editor using "Abilities - Normal". I failed again.

I am just wondering why the levels don't change.

Here are the triggers :

Thanks in advance!

There's a bug in mana and life bonus abilities. Increasing their level doesn't work, but when removing an ability, it decreases mana/life according to the current level. For example:

Mana(+1) is an ability with 0 bonus mana at level 1, and 1 bonus mana at level 2.

Add ability Mana(+1) to u
increase level of Mana(+1) for u
Remove Mana(+1) from u

That code adds 0 mana (according to level 1), but removes 1 mana (according to current level, 2). You can use this bug to your advantage to decrease mana permanently.

So i need to add the mana decrease abilities when the mana needs to be decreased, set the level to the accurate one and then remove them?

EDIT : I MADE IT!!! IT WORKS!!! THANKS A LOT, MAN! ))
