Wrong object always Instantiated

Okay, so I'm working on a system where if a player destroys an object, they may then place duplicates of that item. If no object has been destroyed, an empty object, or airBlock, is placed. I'm currently having an issue where no matter what, the empty object is always placed instead of the intended block. The following script is on every block, and handles destroying the objects and the like.

 var targeted : boolean = false;
 var destroyOrPlace : int = 1; //1 = null, 2 = place, 3 = destroy
 var delayTicks : int = 0;
 var objToLoad : GameObject;
 public var delayTotal : int;
 public var dirtBlock : GameObject;
 public var stoneBlock : GameObject;
 public var nullBlock : GameObject;
 
 function Update () {
     if (targeted == true){
         if (destroyOrPlace == 3)
         {
             delayTicks = delayTicks + 1;
             Debug.Log("ticks updated ");
         } else if (destroyOrPlace == 2)
             {
                 delayTicks = 0;
                 Instantiate(MainScript.inventoryStore[MainScript.selectCol, MainScript.selectRow], transform.position, transform.rotation);
             }
 
     } else {
         delayTicks = 0;
     }
     if (delayTicks == delayTotal) {
         if (MainScript.inventoryStore[MainScript.inventoryCol, MainScript.inventoryRow] == null){
             if (gameObject.name == "Dirt-Block (Clone)"){
                 objToLoad = dirtBlock;
                 MainScript.inventoryStore[MainScript.inventoryCol, MainScript.inventoryRow] = objToLoad;
             } else if (gameObject.name == "Stone-Block (Clone)"){
                 objToLoad = stoneBlock;
                 MainScript.inventoryStore[MainScript.inventoryCol, MainScript.inventoryRow] = objToLoad;
             } else if (objToLoad == null) {
                 objToLoad = nullBlock;
                 MainScript.inventoryStore[MainScript.inventoryCol, MainScript.inventoryRow] = objToLoad;
             }
         }
         Destroy(gameObject);
         Debug.Log("Destroyed");
     }
 }

Any help would be greatly appreciated, and I'm more than happy to provide additional information.
