    While the user checked the checkbox, it will not appear that row on the next Run.
    I have no idea what you mean by: "appear that row on the next run". Can you explain what is happening because I am unclear.

    When asking for help, please follow these guidelines to receive better and more prompt help:
    1. Put your code in Java Tags. To do this, put [highlight=java] before your code and [/highlight] after your code.
    2. Give full details of errors and provide us with as much information about the situation as possible.
    3. Give us an example of what the output should look like when done correctly.

    Looks like it's reading a name, a number, and a time.
