Help with script

Thank you for willing to help a n00b...
Hopefully u are willing to bear with me

I understand all the variables in src_readme.txt as well as those in src_ups_rates.class.php (which I assume are not needed as passed by src_readme.txt.I also understant how to feed it variables.

Using src_readme.txt as an example/sample:
1. I assume src_ups_rates.class.php must be included.
2. What is the output?

If I make a test page from src_readme.txt, include src_ups_rates.class.php, and run it, I get no output, not even an error.

Any advice?
