Help with coin pick up script

Im new to unity and making scripts.
Im trying to make a script to pick up my coins but I keep getting 3 errors that i cant seem to fix.
here are the errors:

error CS0119: Expression denotes a type', where a variable’, value' or method group’ was expected

error CS1502: The best overloaded method match for `UnityEngine.Object.Destroy(UnityEngine.Object)’ has some invalid arguments

error CS1503: Argument #1' cannot convert object’ expression to type `UnityEngine.Object’

and here is my code for the coins

using UnityEngine;
using System.Collections;

public class CoinPickup : MonoBehaviour {

	public int pointsToAdd;

	void onTriggerEnter2D (Collider2D other)
		if ( == "Character") {
			ScoreManager.AddPoints (pointsToAdd);
			Destroy (GameObject);

In the line Destroy(GameObject) you are trying to destroy the class GameObject instead of a variable just change that to Destroy(gameObject);

Also, I am not sure if ScoreManager.AddPoints is a static method or not, if it is not then you will need to create a variable for the ScoreMananger in the script and drop in the score manager object inside unity editors inspector.
