Expected Null Pointer - Please help

Hi , I am trying to plot the data with the country that the user has entered.

My data is formatted in the following way.

Country ,1975 ,1976 ....2014 ;
Afghanistan, 23, 24 ....40.

I want to plot the row data with the code below but I am getting Null Pointer Exception. I can't see where I have gone wrong. Can someone please help me ?

import org.gicentre.utils.stat.*;
import org.gicentre.utils.gui.*;
XYChart Chart;
Table Men ;
TextInput textInput;
float[] yearstoplot = new float[40];

    void setup()
    {
      size(1000, 1000);
      Table Men = loadTable ("Mendatare.csv","header,csv");
      Chart =new XYChart(this);
      Chart.setMaxX(2015);
      Chart.setMinX(1974);
      Chart.setXFormat("####");
      Chart.setMaxY(30);
      Chart.setMinY(18);
      Chart.showXAxis(true);
      Chart.showYAxis(true);
      Chart.setPointColour(color(180,4, 110));
      Chart.setPointSize(5);
      Chart.setLineColour(color(180,4, 110));
      Chart.setLineWidth(2);
      textSize(20);
      PFont fonttextbox = createFont("BodoniMT-48",14);
      textInput= new TextInput(this,fonttextbox,14);

     for (int i=0; i<yearstoplot.length; i++)
      {
        yearstoplot[i] = (i+1975);
      }
      println(yearstoplot);

    }


    void keyPressed ()
    {
     textInput.keyPressed();

     if  (keyCode ==ENTER))
      {
            String countrytoplot = textInput.getText();
            TableRow target = Men.findRow(countrytoplot, "Country/Region/World"); // here is the problem
             float x0 = target.getFloat(3);  //get value from column 3
             float x1 = target.getFloat(4);
             float x2 = target.getFloat(5);
             float x3 = target.getFloat(6);
             float x4 = target.getFloat(7);
             float x5 = target.getFloat(8);
             float x6 = target.getFloat(9);
             float x7 = target.getFloat(10);
             float x8 = target.getFloat(11);
             float x9 = target.getFloat(12); //get value from column 12

             float[] datatoplot = {x0,x1,x2,x3,x4,x5,x6,x7,x8,x9}; //aggregate the values

             Chart.setData(yearstoplot,datatoplot);
      }
     }

    void draw()
    {

      background(255);


      fill(0);
      textAlign(CENTER);
      text("Obesity over the years for countries",300, 20);

      strokeWeight(2.0);
      stroke(40);
      fill(0,200);
      rect(770,20,215,60,8);
      textAlign(RIGHT);
      fill(0);
      textSize(10);
      text("Please type in a country name", width-50,30);
      textInput.draw(780,40);
      Chart.draw(30,80,width-400,height-300);
    }

Is there a better way of doing it ?
