Drop item if hero was item already

[NoAmmoSrry]

I need a trigger for when a hero picks up an item, and he already has that item OR another type of item, he will drop the item he was picking up and a message pops up saying Blah blah blah to that player.


Will rep and give credit anyone who can create me it first, i tried several times and fail


Event
Unit - A unit aqcuires an item

Condition
(Item class of (Item being Manipulated)) Equal to Artifact

Action
If ((((Triggering unit) has an item of type (Random level -1 Artifact item-type)) Equal to True) and (((Triggering unit) is A Hero) Equal to True)) then do (Hero - Drop (Item being manipulated) from (Triggering unit)
^^
Code fail.

Need help.

I used this

• Events - A unit acquires an item
• Conditions - Item type is an artifact
• Actions -
  • If "herohasweapon" = true
  • Then - drop item being manipulated
• Else - set "herohasweapon" = true

and

• Events - A unit losses an item
• Conditions - Item type is an artifact
• Actions - Set "herohasweapon" =true"

If your using it fore more than one unit, then use arrays
'

• Weapon
  • Events
    • Unit - A unit Acquires an item
  • Conditions
    • (Item-class of (Item being manipulated)) Equal to Permanent
  • Actions
    • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
      • If - Conditions
        • HeroHasWeapon[(Player number of (Owner of (Hero manipulating item)))] Equal to True
      • Then - Actions
        • Hero - Drop (Item being manipulated) from (Hero manipulating item)
        • Player Group - Add (Owner of (Hero manipulating item)) to MessageGroup
        • Game - Display to MessageGroup the text: (You may not have more than one weapon at a time! |cffffcc00 + ((Name of (Item being manipulated)) + |r has been dropped!))
        • Player Group - Remove all players from MessageGroup
      • Else - Actions
        • Set HeroHasWeapon[(Player number of (Owner of (Hero manipulating item)))] = True

and this for loss of weapon

• Weapon Loss
  • Events
    • Unit - A unit Loses an item
  • Conditions
    • (Item-class of (Item being manipulated)) Equal to Permanent
  • Actions
    • Set HeroHasWeapon[(Player number of (Owner of (Hero manipulating item)))] = False
