Element undefined in url

Question

Hi-
I've been assinged to create some .cfm screens for our web
page. I have absolutely NO Cold Fusion or HTML background. I do
have some introductory C++, C# and VB background. I'm using
Dreamweaver to create the pages with ColdFusion.
Our website is used to view data, not to submit any
infomration on forms. The first time a user hits my form called
detail_staging.cfm an SQL statement runs that passes three
variables from the previous screen using:
SELECT stuff
FROM stuff's table
WHERE card_data.card_year = <CFQUERYPARAM value="#URL.FY#"
CFSQLTYPE="cf_sql_char"> AND
card_data.card_month= <CFQUERYPARAM value="#URL.MON#"
CFSQLTYPE="cf_sql_char"> AND
agencydim.agy_agency_name=<cfqueryparam value="#URL.AGN#"
cfsqltype="cf_sql_char">
This works great and displays informtion based on year, month
and agency. I then want the user to be able to change the month,
but keep the year and agency. I added:
<FORM action="detail_staging.cfm" method="get">
<div align="center"><span
class="page_text_bold">Select Month:</span>
<select name="Month"
class="page_text_side_header_content">
<cfoutput query="Month">
<option
value="#CALENDAR_MONTH#">#CALENDAR_MONTH#</option>
</cfoutput>
</select>
<input type="submit" value="go">
</div>
</FORM>
CALENDAR_MONTH is populated in the drop down based on the
query 'Month'
HERE'S THE PROBLEM:
When I try to change the month, I get "Element FY is
undefined in URL" How do I keep the variable value for FY and AGN
that came through the first time the page loaded and change only
the month?
I've been trying to find an answer to this for a day and a
half now and I'm hoping that you all can help me.
Thank you very much,
Wendy

Thanks for your reply. I'm still not getting it. The stuff I
looked up
says to put an input inside the form tag, but when I do that,
it wants a
name - so I named it-
Now, it doesn't display anything. Is there something I'm
missing or a
more specific direction you can point me in.
Did you also put it into the <cfoutput> block so that
the url variable
is resolved into it's value?
<FORM action="detail_staging.cfm" method="get">
<div align="center"><span
class="page_text_bold">Select Month:</span>
<select name="Month"
class="page_text_side_header_content">
<cfoutput query="Month">
<option
value="#CALENDAR_MONTH#">#CALENDAR_MONTH#</option>
</cfoutput>
</select>
<cfoutput><!--- This block passes through the other
form values --->
<input type="hidden" name="FY" value="#url.fy#">
<input type="hidden" name="AGN" value="#url.AGN#">
</cfoutput>
<input type="submit" value="go">
</div>
</FORM>
You will also need your select name to match the url name you
use in the
query. They both need to be either "MON" or "Month".
