Trigger Help plz

Well in a earlier post I stated I needed help with a triggere invloving a item setting it out

If someone could write out how I could set this trigger up it would be alot of help


Item1 is not in Region1 anymore, wait 30 seconds then create Item1 in Region1

and make it so it always does this trigger

Thanks in advance AGAIN :D

Event: A Unit leaves region 1
Conditions: My socks are purple
Actions:
Pick every unit in region 1 and do If picked unit = item, set variable booleanItemChecker=True, else Do Nothing.
if booleanItemChecker=False, create item at center of region 1.

That's pseudo-trigger-speak, but it's enough to figure out the exact syntax by.
The event will fire whenever a unit leaves your region, which should be what you need, since the item can't disappear unless someone came in and got it, and then left.

thanks and all but if it isnt a problem could you like do the trigger in world edit and paste it as text here? because im confused, and im using RoC World Edit btw

Thanks, and if you dont have time thanks anyway...
