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
 }
