Question about adding an on-site search function - China DOS Union Forum

All you network experts:
Hello! I've recently been working on the "New Era of DOS" website. I wanted to add an on-site search function, just like the one on webmaster Wengier's "New DOS Age" homepage, but no matter what I do, I just can't get it to work! Webmaster Wengier told me that his on-site search function was registered on a foreign website that specially provides free registration service for personal site search engines. Here is the address: www.picosearch.com So I registered one too, but after adding the link address into the form field, it still just won't work, and it can't search! When I click the "Search" button on the webpage, it returns the following error message:
Improper Call to www.PicoSearch.com

You have reached the PicoSearch Search Engine hosting service. You must contact the webmaster for the site that you were trying to search. Their HTML code has not properly accessed any PicoSearch account in our files. Thank you.

I don't know what's going on here. I hope all of you can give me some advice, thanks!

It's saying the HTML code isn't set up correctly! Can you post the HTML code here so we can take a look?

The homepage "form" code is as follows:

*The following is quoted from Wengier's post at 2003-5-25 11:20:11:* No! Where exactly should this line of code be added in the above "form"?
