Error reading in file data on second entry and save of the data

Question

Hi,
I'm trying to write a class that will save two integers and a string to a text file, which can later be searched. Both integers and the string are input by the user in the main class via the keyboard. The file is saved as follows,
100 1
901,111,offer releaseThe first line represents the maximum number of videos, and the current number of videos in the list. The second integer on the first line is automatically incremented to represent the correct number of video copies.
When the test main class is run again to allow the user to enter a second line of data, it returns with the following error,
Error in SimpleInput.readInt() - digit expected
,111,offer releaseWhy is it unable to find the first integer on the second line?
My constructor for the class is as follows,
public Video(int refNum, int titlerefNum, String filmOffer) {
        referenceNumber = refNum;
        titleReferenceNumber = titlerefNum;
        String[] words = filmOffer.split(",");
        videoOffer = words[0];
    }and my test main class is,
import simplejava.*;
import videos.*;
import java.io.*;
public class AddVideo {
    public static void main(String[] args) {
        //String film, actor1, actor2, director, title;
        int videocodeNum, titlecodeNum;
        String currentvideoOffer;
        SimpleReader keyboard = new SimpleReader();
        SimpleWriter screen = new SimpleWriter();
        SimpleReader inFile = new SimpleReader("title_test.txt");
        SimpleReader inFile2 = new SimpleReader("video_test.txt");
        TitleList titles = new TitleList(inFile);
        VideoList videos = new VideoList(inFile2);
        videocodeNum = keyboard.readInt("Reference Code for the Video?");
        titlecodeNum = keyboard.readInt("Reference Code for the Title?");
        currentvideoOffer = keyboard.readLine("Current Video Offer Code?");
        videos.add(new Video(videocodeNum, titlecodeNum, currentvideoOffer));
        screen.println(videos);
        Title search = titles.lookUp(titlecodeNum);//searches the title_test.txt file to find
        if (search == null)//the title code for the relevant number.
            screen.println("Not found");
        else screen.println(search);
        SimpleWriter outFile = new SimpleWriter("video_test.txt");
        videos.saveTo(outFile);
        outFile.close();
}Any help or advice appreciated!!
