Expression denotes a 'type', where a 'variable', 'value' or 'method group' was expected, and 2 other errors.

I get these errors:
Expression denotes a ‘type’, where a ‘variable’, ‘value’ or ‘method group’ was expected
loaded method match for ‘UnityEngine.GUI.Password Field(UnityEngine.Rect, string, char)’ has some invalid arguments
Argument #1’ cannot convert object’ expression to type UnityEngine.Rect

My code was working before, but because I took out the MonoBehaviourGUI and switched it with GUI.ButtonRect, all these errors happened. I switched because it kept flashing up annoying console errors on my phone. Here’s the code:

using UnityEngine;
using System.Collections;
using Prime31;
using Prime31.WinPhoneEssentials;


public class Photo : MonoBehaviour
{
	public GameObject quad;

#if UNITY_WP8
	

	void Start()
	{
	}

	
	void OnGUI()
	{
		
		
		if(GUI.Button(Rect(10,10,70,70), "Select Enemy" ))
		{
			Sharing.promptForPhoto( true, ( didComplete, photoBytes ) =>
			{
				Debug.Log( "photo chooser result: " + didComplete );

				if( didComplete )
				{
					Debug.Log( "photo chooser successful. image size: " + photoBytes.Length );
					// we process the image in a coroutine so that it happens on the proper Unity thread
					StartCoroutine( loadRawPhotoToTexture( photoBytes ) );
				}
			});
		}

		
	}


	private IEnumerator loadRawPhotoToTexture( byte[] photoBytes )
	{
		yield return null;

		var tex = new Texture2D( 0, 0 );
		tex.LoadImage( photoBytes );
		quad.renderer.material.mainTexture = tex;
	}

#endif
}

Rect(…) is missing a “new” keyword

In line 23 you forgot the “new” keyword:

 if(GUI.Button(new Rect(10,10,70,70), "Select Enemy" ))
