3 drop down boxes

[MasterChief]

I have 3 drop down boxes on the same page. Each one is being populated
by a database. One is called Location, One is called Device and the
other one is called Job Title. When the user selects something from one
of the drop down boxes I would like it so it automatically calls the
phonelist.asp and passes the variable. What is the best way to do it so
I have 3 seperate drop-down boxes that just send their variables.
Should I do one form that includes all boxes or one form for each
drop-down box? How do I grab the variable from the drop-down box?

Sorry I probably didn't explain myself very well. I don't really want
the drop-down boxes to be dependant on each other. I have Three boxes
named Location, Device and Job Title. When the user choses something
from say the Location list I want onChange to call the phonelist.asp
and just send the Location variable that I chose. If the user chooses
something from the Device list I want it to call phonelist.asp and only
send the Device that the user chose. I just don't understand the best
way to implement it and also how to have phonelist check against the
Device sent if Device is sent or Location if Location is sent.

You have to post to a page to enable this to happen. If you don't want to
submit your page every time the dropdown selection changes, you can use
XMLHTTP to submit to a server-side page from client-side code. Do a google
for that term and followup in a client-side scripting newsgroup such as
..scripting.jscript

This is really a client side issue.

Does it matter if the selection is in the URL, or do you require a post
to your page? If it can be in the URL, just call a function such as

function dochange( element, page){
document.location.href=page + "?var=" + element.value;
}

and on the select control do an onchange:

<select onchange="dochange(this, 'mypage.asp')">
<option>....
</select>

So what you'll do is pass the page that you want to go to as the 2nd
parameter.

Here's a little something I put together that may hopefully give you
some ideas about how to construct a SQL statement with a variable number
of criteria:
