OnMouseEnter OnMouseExit, and Event Triggers Not Working?

Questions & Answers
1

I’ve tried everything, read all docs, and questions/answers i could find, Tried using those methods, Still didnt work at all.
I tried ‘OnMouseEnter’ and ‘onMouseEnter’ same thing for the OnMouseExit, Still doesnt work.

Edit: My objects have BoxColliders on them, along with rigidbody.
I get no errors. Only problem is ‘OnMouseEnter();’

Code[Unity 5] (C# Because I don’t like using JS):

using UnityEngine;
using System.Collections;
using UnityEngine.UI;
public class PickupItem : MonoBehaviour {

public Text text;
public string itemname;
public string hoverMessage;
public string pickupMessage;
public bool mouseHover;
public int itemID;
public Inventory inv;
public GameDB invAdd;
public bool[] items;
public int itemAmount;
public bool pickedupItem;
private float texttime;
public float textTime;

void Start () {
	texttime = textTime;
	inv = GameObject.FindObjectOfType<Inventory> ();
	invAdd = GameObject.FindObjectOfType<GameDB> ();
	text = GameObject.Find ("ItemPickupText").GetComponent<Text>();
}

void Update () {
	if (pickedupItem) {
		text.text = "" + pickupMessage + " [" + itemname + " x" + itemAmount + "]";
		texttime -= Time.deltaTime;

		if (texttime <= 0) {
			texttime = textTime;
			text.text = "";
			pickedupItem = false;
		}
	}

	if (!mouseHover) {
		text.text = "";
	}

	if (mouseHover) {
		if (Input.GetMouseButton (0)) {
			this.gameObject.transform.position = Input.mousePosition;
		}
	}
}

//Backup if Event Trigger Doesnt work
public void OnMouseEnter(){
	Hover (true);
}
public void OnMouseExit(){
	Hover (false);
}

public void Hover(bool h){
	mouseHover = h;

	if (mouseHover) {
		text.text = "" + hoverMessage + " [" + itemname + " x" + itemAmount + "]";
		if (Input.GetKeyDown (KeyCode.E)) {
			if (items [0] = true) {
				invAdd.AddWaterBottle (itemAmount);
				pickedupItem = true;
			}
			if (items [1] = true) {
				invAdd.AddChocolateBar (itemAmount);
				pickedupItem = true;
			}
			if (items [2] = true) {
				invAdd.AddCannedBeans (itemAmount);
				pickedupItem = true;
			}
			if (items [3] = true) {
				invAdd.AddGauze (itemAmount);
				pickedupItem = true;
			}
			if (items [4] = true) {
				invAdd.AddAxe (itemAmount);
				pickedupItem = true;
			}
		}
	}
}
}

Did you set the collider components to IsTrigger?

“MonoBehaviour.OnMouseEnter() is called on Colliders marked as Trigger if and only if Physics.queriesHitTriggers is true.” (Unity - Scripting API: MonoBehaviour.OnMouseEnter())
