A new expression requires () or [] after type

I keep on getting the above error when I try to declare the Dictionary. How can I fix this?

sing UnityEngine;
using System.Collections.Generic;

public class inventoryV1 : MonoBehaviour {
	public static bool inventoryOn = false;
	//GUI FONT AND SIZE
	private Vector2 windowPosition = new Vector2(300,0);
	private Vector2 windowSize = new Vector2(745, 750);

	private Vector2 closeSize = new Vector2(24,24);

	private Vector2 inventoryTitlePosition = new Vector2(245,11);
	private Vector2 inventoryTitleSize = new Vector2(125,50);

	private Vector2 playerTitlePosition = new Vector2(17,11);
	private Vector2 playerTitleSize = new Vector2(100,50);

	private Vector2 craftingTitlePosition = new Vector2(17,414);
	private Vector2 craftingTitleSize = new Vector2(125,40);

}

Your trying to declare it Twice. Once at the top and then again when you fill it at the bottom.

//DICTIONARY
inventoryNameDictionary = new Dictionary<int, string>()
{
//THE ERROR IS RIGHT HERE
(0, string.Empty),

Remove the Dictionary declaration like above.
