How to update database with a select box

Question

I'm hoping someone can/will help me with a new feature I'm
trying to add to my web site. I'll summarize what I'm working with
and then proceed to what I'd like to do. This is the web site I'm
working on: www.truckerstoystore.net
I have a database for the Truck of the Week set up with the
information that is output on each page in the left column and
on the Truck of the week page itself. I add new Truck of the
Week (TOW) entries via a form I've put together. Right now, in
order to change the current TOW, I have to manually go into my
template and change the ID (which is automatically assigned when
the record is created, and thus makes it unique) in my SQL which
currently reads
SELECT *
FROM truckofweek
WHERE ID="4"
to the ID of the current TOW.
What I want to be able to do is create a new form that will
allow me to select the TOW entry that I want to be displayed from a
select box (drop down box). I have a good idea of how to populate
my select box, but don't know how to get it to work. My first idea
was to update the table in the database (Access) manually with a
new column called currentTOW, with values set to a Yes/No type,
with default values set to "No". Then I would use my form to set
the value for one of them to "Yes" so I could set my SQL to 'WHERE
currentTOW ="yes" ' I would also make a <cfif> statement that
checks for entries marked "Yes" and changes them to "No" when the
form loads to avoid setting 2 entries to "Yes" and my page thus
attempting to load 2 TOW entries.
My problem is, I don't know how to do any of this. I hope
I've described this situation well enough. I know there has to be
at least one guru on here that can help me. Any assistance would be
greatly appreciated.

Hey,
Thanks for replying. That sounds like a good idea, but I
don't know how to do it.
I started working on a new idea, where I have a second table
in the same datasource set up called currentTOW, with one field
called currentTOW and only one record. The idea is to send the
string of the "owner" field from the select box, which is populated
from the table called truckofweek to this one cell in the
currentTOW table.
This way, in my page which will display the data, I have 2
querys. The first pulls the data in the single cell from currentTOW
and outputs its string into the second query. I've attached the
code below. I get an error when I try to display the page, see the
error here:
www.truckerstoystore.net/currentTOW2.cfm.
However, the SQL looks like I want it to look, as "WHERE Owner =
Craig Carp" is essentially the same record that it displays now in
the live page "/currentTOW.cfm" only the SQL currently reads "WHERE
ID = 4" (4 and Craig Carp are part of the same record).
Here is the link to my form:
