Unity help code keeps coming back with a error

[LauTam]

Hello,

somehow my code keeps getting a error in Unity. I'm a newbie in C++ so I have tried some alternatives and it didn't work. So if anybody can help me, I would be grateful. The use of this code is that I can scale a object with touch on a smartphone.

 using UnityEngine;
using System.Collections;




public float (defaultScaleX , defaultScaleY , defaultScaleZ)
public float (currentScaleX, currentScaleY , currentScaleZ)
public GameObject (mBundleInstance = null)


		if (Input.touchCount > 0 && Input.GetTouch(0).phase == TouchPhase.Moved){
		Vector2touchDeltaPosition = Input.GetTouch(0).deltaPosition;
		//Debug.Log( mBundleInstance.transform.rotation.y + ":"+touchDeltaPosition.x );
		mBundleInstance.transform.Rotate(Vector3.up * -touchDeltaPosition.x * Time.deltaTime * rotationSpeed);
		}
		if(Input.touchCount == 2){ 
		Touchtouch0 = Input.GetTouch(0);
		Touchtouch1 = Input.GetTouch(1);
		if(touch0.phase == TouchPhase.Moved && touch1.phase == TouchPhase.Moved){
			Vector2prevDist = (touch0.position - touch0.deltaPosition) - (touch1.position - touch1.deltaPosition);
			Vector2curDist = touch0.position - touch1.position;
			floatdelta = curDist.magnitude - prevDist.magnitude;
			if(delta > 0){
				if(defaultScaleX >= currentScaleX* 4){

				}
				elseif(defaultScaleX < currentScaleX - 0.1){

				}
				elseif(defaultScaleX >= currentScaleX){

					defaultScaleX = defaultScaleX + 0.03f;
					defaultScaleY = defaultScaleY + 0.03f;
					defaultScaleZ = defaultScaleZ + 0.03f;
					mBundleInstance.transform.localScale = newVector3(defaultScaleX,defaultScaleY,defaultScaleZ); 
				}
				else{

					defaultScaleX = defaultScaleX + 0.03f;
					defaultScaleY = defaultScaleY + 0.03f;
					defaultScaleZ = defaultScaleZ + 0.03f;
					mBundleInstance.transform.localScale = newVector3(defaultScaleX,defaultScaleY,defaultScaleZ); 
				}
			}
			elseif(delta < 0){

				if(defaultScaleX <= currentScaleX){

				}
				elseif(defaultScaleX > currentScaleX){

					defaultScaleX = defaultScaleX - 0.03f;
					defaultScaleY = defaultScaleY - 0.03f;
					defaultScaleZ = defaultScaleZ - 0.03f;
					mBundleInstance.transform.localScale = newVector3(defaultScaleX,defaultScaleY,defaultScaleZ);
				}
			} 
		}
