Need Help with a Spell Cap Trigger

[Firespark]

I have a map where the heroes can buy their spells but the way I have it set up in the triggers is that when they buy an item the items is removed from their inventory and an spell is added to their abilities.
The problem is I only want them to be able to buy 4 spells. I can't figure out how to stop them from buying more than 4 spells. Can some one please help?

Well, every hero has an "inventory" ability, you can change it's item slots to 4. If you don't like that way, well, you can trigger it, the trigger should fire when the unit aquires an item, conditions if the number of items in the unit is more than 4, and the action would be to remove that item and give back the money?

The item is removed from their inventory as soon as they get it. You dont even get to see the item. I just more or less use it as a dummy.

I meant removing the spell sorry, is my first suggestion ok then?

But how would I go about doing that? I was really hoping that wouldn't have to redo all my triggers for the spells.

I think you don't have to redo all the spells, just create a trigger which would detect the 5th item in the inventory (the event will detect it even if it's removed instantly) and remove the corresponding ability. Sorry for such unclear suggestions, I'll write the code, but now I must hurry to school.
