Limiting Item Classes

Okay so i'm trying to limit each hero to only 1 item if they belong to these classes: Permanent, Artifact, and campaign. My trigger is:

I think the problem lies in the integer A part. What happens is when I try to pickup a weapon with an empty inventory it drops, but when I have a potion in my inventory the trigger doesn't do what it's supposed to do!

You have to use a For Integer A action to loop through 1-6 so that you can check the slots properly. Simply using Integer A by itself will simply use the value it was set to last in a previous For Integer A iteration.

So what do I change?

Put your actions in a For Integer A action and set it to loop through 1-6.

Thanks sentryIII ur da bomb :D

Anyways while I was in bed I did a rem cycle and figured out the loop while trying to fall asleep, but now I know for sure.
Side Note: Do you think "better" and harder when you're trying to fall asleep?

Okay now it drops the item even if he has an empty inventory slot, I think because when the item is picked up it detects that picked up item. Heres the new trigger:

How strange. I have just been researching sleep as I have found that I have a disorder. I say yes to the thinking thing!
On your first condition, I think removing the "item being manipulated" might help. It looks like you're checking the class of the item being picked up, which is then added to the inventory, and the you check the item in the inventory, which returns true. So in any case, the item will be dropped.

Offtopic:
Lol, I got a lot of my best ideas just when trying to go to sleep! Guess its common.

What can I do to make the trigger work? The damn GUI doesn't let me check the number if item classes in an inventory, I think.

This may be crap, but try reversing this:
(Item-class of (Item being manipulated)) Equal to (Item-class of (Item carried by (Hero manipulating item) in slot (Integer A)))
