How to assign a gameObject to a child gameObject?

I'm trying to take a gameobject in a script, and assign it to a gameObject that is childed under a parent.

Code (CSharp):

1. void SelectPillar()
2.     {
3.         GameObject GO = GameObject.Find("Pillars"+pillarEnemy+"(Clone)");
4.         int GOChildNum = GO.transform.childCount;
5.         int randomSpawn = Random.Range (0,GOChildNum);
6.         goodPillar = GO.transform.Find("Pillar"+randomSpawn+"(Clone)");
7.     }

goodPillar is a gameObject, GO is the parent that has already spawned ingame, and "Pillar"+randomSpawn+"(Clone)" is the child.

I'm getting an error that says I cant assign a gameobject to a transform, but I don't see how the child is a transform. It should just be a gameObject.

 

i think the transform.Find returns a transform
http://docs.unity3d.com/ScriptReference/Transform.Find.html

 

Then how am I supposed to access Child GameObjects and manipulate them?

Edit: Nevermind. Apparently you can create a transform of said child, then access the transform.gameobject.

Seems like a very complicated way to access a child. But whatever.

 

Code (CSharp):

1. goodPillar = GO.transform.Find("Pillar"+randomSpawn+"(Clone)").gameObject;

 

That works too, thank you.
