Selecting different spinner option doesn't update calculation

[brisk]

Hey guys,

I have a simple spinner which has several number options. I want to just select a number and then it does some math to that number and outputs it in a text box. For some reason it's only doing math on the 1st entry in the list and if you change it doesn't update.

Any ideas?

package placeorder.com;

import java.util.Random;

import android.app.Activity;
import android.os.Bundle;
import android.widget.Spinner;
import android.widget.TextView;

public class Time extends Activity{   
   
   double totalhours, cost;
   int price;
   TextView total, orderid;   
   
   @Override
   public void onCreate(Bundle savedInstanceState) {
      // TODO Auto-generated method stub
      super.onCreate(savedInstanceState);
      setContentView(R.layout.time);
      
      Spinner spinhours = (Spinner) findViewById(R.id.sp_hours);
      total = (TextView) findViewById(R.id.tv_total);   
      orderid = (TextView) findViewById(R.id.tv_orderid);   
      
      Random order = new Random();
      int randomorder = order.nextInt(9999);      
      order.nextInt(9999);            
      orderid.setText("Order ID: "+randomorder);      
      
      price = 5;                 
      String hours = spinhours.getSelectedItem().toString();
      totalhours = Integer.parseInt(hours);      
      cost = totalhours * price;            
      total.setText("£" + cost);            
      
      
   }


   
}
