Go read references quick reference and learn how to do complex data structures. Then write toy examples and print them out with Data::Dumper until you are sure you have absorbed that. Then take your problem and break it into small pieces. Code each piece. Test that it does what you expect and has the values you expect. Put it together and test it again.

That is a likely path to success.

Continuing to try to solve the whole problem at once while you are unsure of basic concepts is not going to work. Trust me. I once had the fun of working with a novice in training. After she had been flailing for a month while getting nowhere I sat down with her and made her break the problem up. Every day I asked her what her plan was for the day and made sure she was working in small pieces. The project was done a week later. I helped her start the same thing with the next. After that she did well.

Divide and conquer. It isn't just useful for Julius Caesar.

• Are you posting in the right place? Check out Where do I post X? to know for sure.
• Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:

  <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>

• Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
• Want more info? How to link or How to display code and escape characters are good places to start.
