Value from Activity A to Activity B returning null

I am trying to get information from Activity B, into Activity A, the problem is that the value that i am getting is returning null for some reason. My code see's how many times you click on the Button and returns the value into my first Activity, at least thats what it is suppose to do. If sombody see's my mistake please tell me, i have class in 5 hours :\

returned.setOnClickListener(new View.OnClickListener() {
            public void onClick(View v) {

                Intent intent = new Intent(Next.this, Hw3Activity.class);
                intent.putExtra("text", counted.getText().toString());
                startActivity(intent);
/*Next is the current activity, Counted is the name of my text box*/
            }
        });
        click.setOnClickListener(new View.OnClickListener() {
            public void onClick(View v) {
                counter++;
            }

This is the Activity i want the information transferred to.

Button change;
    TextView text;
    int number;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        change = (Button) findViewById(R.id.change);
        text = (TextView) findViewById(R.id.count);

        String s1 = getIntent().getStringExtra("Textview01");
        text.setText("You clicked the button " + s1 + " times.");

        change.setOnClickListener(new View.OnClickListener() {
            public void onClick(View v) {
                Intent intent = new Intent(getApplicationContext(), Next.class);
                startActivityForResult(intent, 0);
/*this button is for going to the 2nd activity,not my problem currently*/
            }
        });
    }

}

try String s1 = getIntent().getStringExtra("text");

Because You are sending string value tag as "text".

In the Activity where you want the info, there is an error. You need to put "text" instead "Textview01".

You can use the following with error control.

Bundle extras = getIntent().getExtras();
if( extras != null){
   String text = extras.getString("text");
}

here's what you are doing wrong:

String s1 = getIntent().getStringExtra("Textview01");

i believe it should be:

String s1 = getIntent().getStringExtra("text");
