objects inside trigers setting it off

[DEMONIAC]

ok here is what im doing in my map i have a few hiden
objects i have a triger to tell evrey one when a player finds this object it says "holy shi* {players name} has found xxxxx"
i want the triger to go off when the player comes upon the object i can get it to work right from one side
but i want it to work when they come upon it from all sides if i make the triger radiuse biger and have the triger over the object it says holy shi* error no unit hase found xxxxx what would be the easyest way to get this to work right

o ya thought about adding more trigers on all sides
but i dont want them to keep going off after they trip one triger
