Problems when reading from the computer memory, information previously got from a file
<p>The problem that I have is that I have writen a code that has to get information from the computer memory. This information has previously got from a ".txt" file and stored in the computer memory in a particular way "simulating a database", but when accessing to the information I have a problem because the code doesn't run in the way I want. Have a look at the code and you will understand what I mean easily.</p>

<p>I enclose a example of ".txt" file that I use and the code I have writen.</p>

<p>Table.txt</p>
