[Trigger] trigger problems

[rasmuz3]

Hi!
I need help with a trigger/some triggers. If I want to be able to buy a item for right hand (its an attachment item) but only once, how do I do?
I don't want a unit to have for example 2 right handed weapons. I also have two-handed weapons, left handed weapons, shields, armor and stuff like that. So how can I make units only wear one left handed and a shield for example? not 2 left handed or a right handed and a two-handed.
Wow, this sounds pretty confusing, but plzz help me with this one.

Maybe I shull tell you what i tested, this is how my trigger looked like, but didn't work. And if it did it would take a loooong time, so plzz help me..

Event: Unit aquires Item
Condition: (Item-type of(Item being manipulated)) Equal to "for example left sword")
((Hero manipulating item) has an item type "left sword" Equal to True
Action: Remove (Item being manipulated)
Display to ("don't know what to do here, I want only the owner of the unit to see this") the text: You can't wear that weapon now!


On the last action, the one with the text (or something close to it) , it would be great if "You can't wear a weapon" came up like when u play wc3 and don't have enough gold to buy something, it comes up in yellow almost in the middle. That would be great.
Now plzz help
