Cannot convert 'UnityEngine.GameObject' to 'UnityEngine.Transform'. error

So the question is the error I’m getting at line 53, column 72. I’m not exactly sure what I’m doing wrong as I’m pretty sure that gameObject.transform is legal.

Here’s the code:

#pragma strict
public var currentBlock : GameObject;
public var rotationOffset : float;
public var currentHand : GameObject;
public var hands : GameObject;

function Start () {

}

function Update () {
			var ray : Ray = Camera.main.ScreenPointToRay(Input.mousePosition);
			var hit : RaycastHit;
		if (Input.GetMouseButtonDown (0)) {
			
			if (Physics.Raycast(ray,hit) ) {
			if (hit.collider.tag == "Detector") {
				//hit.collider.name
				//hit.collider.tag
				//hit.point
				//hit.collider.gameObject.transform.position
				//Destroy (hit.collider.gameObject);
				var clone : GameObject;
				var vec = currentBlock.transform.rotation.eulerAngles;
				vec.x = vec.x + rotationOffset;
				clone = Instantiate(currentBlock, hit.collider.gameObject.transform.position, Quaternion.Euler(vec));
				}
			}
		}
		if (Input.GetMouseButtonDown (1)) {
			
			if (Physics.Raycast(ray,hit)) {
				if(hit.collider.tag == "Ground") {
					Destroy(hit.transform.gameObject);
			}
				
			}
		}
		if (Input.GetKeyDown("r") && rotationOffset != 360){
			rotationOffset = rotationOffset + 90;
		} else {
			if (Input.GetKeyDown('r') && rotationOffset == 360){
			rotationOffset = 0;
			}
		}
		if (Input.GetKeyDown("e")) {
			if(currentHand != null) {
						currentHand.gameObject.transform.parent = null;
					}
			if (Physics.Raycast(ray,hit)) {
				if(hit.collider.tag == "Movable") {
					currentHand = hit.collider.gameObject;
					currentHand.transform.parent = hands;
				}
			}
		}
	}

Like Eric5h5 mentioned, you have to set an Transform as a parent, not a Gameobject, like your hands variable. Do something like:

currenthand.transform.parent = hands.transform;

But I don’t think you can set the parent of an Gameobject like that anymore. You have to do:

currenthand.transform.SetParent( hands.transform );

Transform.parent must refer to a Transform, not a GameObject.
