Collider not detecting trigger

I have an object that when it detects the trigger im suppose to be able to place it. But no matter what I seem to do is doesn't respond. So I took my script and put it on my player and it detected the player perfectly. The object I place has a collider not triggered. Where im trying to place is triggered. Im lost :(

Here is the script im using:

 #pragma strict
 var intendedPosName : String;
 var canPlace        : boolean = false;
 function Start () 
 {
     canPlace = false; // This is so that game doesn't start out letting you place the object anywhere.
 }
 
 function Update () 
 {
     
 }
 function OnTriggerEnter(col : Collider)
 {
     if(col.name == intendedPosName)
     {
         print("I entered");
     }
 }
 function OnTriggerStay(col : Collider)
 {
     if(col.name == intendedPosName)
     {
         canPlace = true;
     }
 }
