Help with moved region doesn't activate when units enter/leaves the region

I have two triggers.

Trigger 1: Every 1 sec. the region is centered on a unit.

Trigger 2: If a unit enters the region it dies.

However, Trigger 2 does not work. Anybody know why?

If I don't move the region (ie. remove Trigger 1) then Trigger 2 works.

Help, please.

(The region is placed in the World Editor and not generated by a trigger)

Events cannot register moved regions. Only trigger actions can. For instance, you can order a unit to moved to a moved region, but you can't tell if he made it there.

use the units comes within range trigger its so much better causes less lag and is a circle and not a square.

Actually as it turned out I found a much better way to accomplish what I was trying.

But thanks anyway. :)
