Hi there,
First off, I assume you meet all the requirements.
1) Create a file
search_form.php and type these up:
2) Create a file
search_results.php and type these up:
3) Create a file (if not yet done)
mp3_search_engine.php and dump all the contents of the code you pasted.
4) Put them all in one folder.
5) Access the search_form.php.
This way you'll see the form and can at least do the search. I tried it, however, and most of the search engines registered here reject GET parameters passed from the function - from external sites, I guess. Some of the engines are no longer available, either. Hence, though the functions does what it's told to, but doesn't serve you well. (Kermit/Oth.net worked fine, just to let you know) For those, sorry, but I can't help you. Good luck.
