    Default search string in a text file

    I want to search for a name of a co ordinate in a text file and then use the x and y values.
    I did the programming in Java ready to program and there it works fine, but when I use the same method in eclipse it gives me the last co ordinates name with no x and y

    Here is the code:

          coordsuk1 =(EditText) findViewById(R.id.etJoin1);
    		searchco1 =(Button) findViewById(R.id.bSearchCo1);
    		searchco1.setOnClickListener(new View.OnClickListener() {
     
    			public void onClick(View v) {
    				// TODO Auto-generated method stub
    				try{
    					File myfile=new File("/sdcard/"+filename.getText().toString()+".txt");
    					FileInputStream filein=new FileInputStream(myfile);
    					BufferedReader br=new BufferedReader(new InputStreamReader(filein));
     
    					String reel = br.readLine ();
     
    	                                int tel = reel.indexOf (" ");
    	                                naamsuk1 = reel.substring (0, tel);
     
    					while (!naamsuk1.equals (coordsuk1))
    	                                {
     
    	                                   reel = br.readLine ();
    	                                   tel = reel.indexOf (" ");
    	                                   naamsuk1 = reel.substring (0, tel);
    	                               }
     
    	                                coordnaam1join = reel.substring (0, tel);
    	                                coordy1 = Double.parseDouble (reel.substring (10, 22));
    	                                coordx1 = Double.parseDouble (reel.substring (26, 36));
     
    					Toast.makeText(getBaseContext(),
    							"Co ord '"+filename.getText().toString()+"' found",
    							Toast.LENGTH_SHORT).show();
     
    				}
    				catch(Exception e){
    					Toast.makeText(getBaseContext(), e.getMessage(),Toast.LENGTH_SHORT).show();
    				}
    				joinIntv1.setText("coordsuk1: "+coordsuk1);
    				joinIntv2.setText("naamsuk1: "+naamsuk1);
     
                                    joinIntv3.setText("coordy1: "+coordy1);
    				joinIntv4.setText("coordx1: "+coordx1);
     
     
    			}
    		});

    o and I get a blank Toast
    The text file looks like this:

    AB -42537.4098 24263.8160
    ST4 -42677.9017 24201.6750
    WODRC -42428.8129 24151.9450
    MGDM -42369.8561 24128.2079
