If it's a non multiple <select> box, then only the selected item gets passed on form submission.
If you have more than one dropdown with the same name, the information gets passed in an array of that name.
In what you have above, you are trying to reference a 2 dimensional array, that won't happen.
if you have <select name="year"> ...... in your html, you can access this by doing this:
if you have more than 1 <select name="year"> ..., you can access what you want by choosing an index like this:
Here is a quick writeup I did:
You can test this by changing the highlighted number to other values to see what happens.
![[monkey]](/data/assets/smilies/monkey.gif "[monkey] [monkey]")
![[snake]](/data/assets/smilies/snake.gif "[snake] [snake]")

monksnake,
Thanks for the code, I tested it. That is pretty handy indeed. I used the wrong verbage to explain what I am trying to do though. I have a list which allows multiple selections to be chosen. I need to be able to capture all of them that the user selects. I tried searching for examples of the code online, but did not find it in regular ASP , but I did see lots of examples of ASP.NET. My old textbook didn't really give any examples. Is the same as the other types? I am getting an error when I try to run the page, but figured I would check my syntax for those first, and then if I get the error again will post it. Thanks.

Here is the code just in case I am not being clear:

Code:
<select name="opt" size="3" multiple>
<option value="AC">AC</option>
<option value="Power steering">Power steering</option>
<option value="Cruise Control">Cruise Control</option>
<option value="Radio">Radio</option>
<option value="Bench Seat">Bench Seat</option>
<option value="Lift Gate">Lift Gate</option>
</select>~E
I modified the code that I wrote yesterday:
I'm not sure exactly how you want to insert these values in a database, but this code shows you how to extract each value selected from the dropdown.

Code:
<%@LANGUAGE="VBScript"%>
<%
dim cheese, rat
rat = Request.Form("rat")
if rat = 1 then
cheese = Split(Request.Form("year"),",")
for each item in cheese
Response.Write item & "<br />"
next
end if
