make item dissapear after x time

[zzyzxroad]

I want my gold dropped to dissapear after 22 seconds. with this trigger it only removes the LAST item created, not all of them.

LVL 6 Bonus
    Events
        Unit - A unit Dies
    Conditions
        (Unit-type of (Triggering unit)) Equal to  Level 1
    Actions
        Set Random = (Random integer number between 1 and 100)
        If (All Conditions are True) then do (Then Actions) else do (Else Actions)
            If - Conditions
                Random Less than or equal to 20
            Then - Actions
                Item - Create Bonus Gold at (Position of (Dying unit))
                Special Effect - Create a special effect at (Position of (Picked unit)) using Abilities\Spells\Other\Levelup\LevelupCaster.mdl
                Wait 22.00 seconds
                [COLOR="Red"]Item - Remove (Last created item)[/COLOR]
            Else - Actions

How would I achieve all the gold to be removed?

Set the item's custom value to 22

Keep periodic active all times
pick every unit matching gold coin type
set custom value = custom value - 1
if custom value = 0 remove picked item

hmm. seems a little complex. I tried Remove random item from map, and repeat it a few seconds later. It seems to work. So now you have to quickly pick up your gold, if not, then it will randomely disappear, then a few seconds more, more will disappear. I think it works good for me.

Thanks for your help.
