Problem passing data to new Activity

Hello, I have been working on an application and have run into a problem that is baffling me. To preface, I've created a ListView and am trying to perform the simple task of carrying a single piece of data to a new Activity upon the clicking of a selection. Here is most of the code from the Activity that is crashing:

Syntax: [ Download ] [ Hide ]

Using java Syntax Highlighting

public class selection extends ListActivity {
        private ListAdapter adapter;
        private Cursor managedCursor;
        /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle icicle) {
        super.onCreate(icicle);
        setContentView(R.layout.selection);
          
        Cursor managedCursor = getContentResolver().query(People.CONTENT_URI, null, null, null, People.NAME + " ASC"); 
        startManagingCursor(managedCursor); 
        
        String[] columns = new String[]{People.NAME}; 
        
        int[] to = new int[] { android.R.id.text1 };
        adapter = new SimpleCursorAdapter(
                this, /* Context. */
                android.R.layout.simple_list_item_1, /* row layout file */
                managedCursor, /* Pass in the cursor to bind to. */
                columns, /* Array of cursor columns to bind to. */
                to); /* Parallel array of which template objects to bind to those columns. */
 
        /* Bind to new adapter. */
        this.setListAdapter(adapter);
 
    }
    
    @Override
    /* Upon clicking a selection, sends the _ID to the "send" screen for retrieving contact data. */
    protected void onListItemClick(ListView l, View v, int position, long id) {
        super.onListItemClick(l, v, position, id);
        Cursor c = managedCursor;
        c.moveToPosition(position);
        Intent i2 = new Intent(this, sendscreen.class);
        i2.putExtra(sendscreen.iD, id);
        startActivity(i2);
    
     
    }
 
}
Parsed in 0.036 seconds,  using GeSHi 1.0.8.4

The crash is happening during the click event, specifically at this line according to the debugger:

Code: Select all: c.moveToPosition(position);

I can't figure out why this is happening. Any help is greatly appreciated!

Nevermind, I went a different route to accomplish this.
