What has this got to do with "onChange method of <select> in Html not working" ?
And what has this got to do with ASP Databases?

You are wiring up a client side event to server side code, this will not work in this implementation.

================================================== =========
I will only tell you how to do it, not do it for you.
Unless, of course, you want to hire me to do work for you.

There are a number of issues with your code.
As Doug points out, you are attempting to use code on the server that isn't available on the server, and code in the browser that isn't available on the browser.

The onChange attribute of the select element will run code (either Javascript or VbScript) in the browser - so your challenge is to make some very simple tests with no extra features (like the CSS and etc).
I would suggest that you write this code as pure HTML with client side javascript (or vbscript) and NO serverside code at all so you can get the feel for how clientside code works. That is - you are using serverside blocks of code througout that are not actually doing anything and in some cases can't even complile. Take out everything that doesn't compile and then add back in the pieces you need.

For example, you need to re-write this (which makes no logical sense):

Code:

<option value="<%itemp=88%>">Test1</option>

as this:

Code:

<option value="88">Test1</option>

and so on...
