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.
