MySql problems

[driveflexfuel]

I have been trying to get this code working and I have hit a stand still. I do not know if it is by my error or the way I am coding the js. Currently it loads correctly half the time and the other half the form shows blank and the load time of each box is slow. If I refresh the page it does not refresh the form data. If there is a better way of coding this other then ajax I am willing to hand out 800 credits for the coding. Any language that works on x10 hosting I am in a crunch to get this finished and it is driveing me nuts.

Here is a line from the database.
year make model engine link to products
"1990","Acura","Integra","4 Cylinder","http://site.com/store"

Edit:
I found the error you can close the thread this is the new code.

var request = false;

try {

  request = new XMLHttpRequest();

} catch (trymicrosoft) {

  try {

    request = new ActiveXObject("Msxml2.XMLHTTP");

  } catch (othermicrosoft) {
