i know this maybe to easy for you, this is what i need to accomplish:

2 list menus

1.- Manufacturer (Honda, Kawa, Susuki)
2.- Model (cr250, cr125,etc..) each manufacturer has their own models
3.- Year(1999.1998,etc..)

So i would like to have the first list menu listing the manufacturers options and when the user click on one another list menu will show or appear or maybe a submit button and then it will populate the MODEL info and the the YEAR, at the end will show a single line of text which will be the part number of the produc

i.e

1.- Manufacturer = Honda
2.- Model = cr250
3.- Year = 1999

Result = Part Number:KHND99

thank you!!

use PHP String Functions to do this...
take a look at this

I got this code from someone that was helping me but i guess he decide not anymore, i am missing the functions.php file i never receive it, here is the code it was given to me:

But i can't make it work, it renders blank!!!!

<?php


//include("functions.php");
//dbConnect();
