hi;
I am trying to make a dynamic website work, and need some help, your help is appreciated.

I am using DWMX and PHP/Mysql,
I have a database conatin of company informaion, name, address and telno, and they are categorized,
here are the tables:
Category: category_id, category_name
Company: company_id,company_name, address, email,etc..
Telno: telno_id, telno( because some company has more than one tel no, so I did a table for telno).

Now, I want to have two drop down list/Menu( category dropdown menu and company dropdown menu) on the search page, and a submit button, but I can't get these two drop down menu work properly, dynamic data show up on the menu but the actual search which should populate the data and show it on Master page does not work,
I have found a tutorial for this example but unfortunately it has been done for DWUD and ASP, I tried it but get errors,
so I am newbie, if you know how to do this I appreciate your help. or if you know a tutorial site having this example for DWMX and php/mysql, appreciate your reply.
here is the tut site for exact search I am trying to make:
