How to limit items?

[pevs]

I want to make it so if ANY unit that gets more than 1 of "XXX item" then the 2nd item will be destroyed so there is only one on the carrier at all times

I can't remember all the the action/condition names but something like this:
Event: A hero acquires an item
Actions: Maybe under hero or item section, do the actions so that it checks if the hero has a same type of item it picked, if it has, remove one of them. Use integer section in condition-The hero has more than 1 item of the type?

Tell me if you need more help.

event: a unit aquire an item
action:
loop a for 1 to 6,
if item carried by (triggering unit/hero manipulating item) in slot a equal to (item being manipulated)
then remove (item being manipulated)
else (do nothing)

something like this ...

The slot the item is in will always be equal to itself... so he'd never be able to pick it up.

remove item being manipulated
loop a for 1 to 6,
if item carried by (triggering unit/hero manipulating item) in slot a equal to (item being manipulated)
then (do nothing)
else (create item for hero[item being manipulated)
