Fk error display on Action page

Question

I have a page that displays the content of a table. If you select one of the items and hit submit, it will navigate to another page that will allow you delete this item. Once the user hits delete the user is directed back to the page that displays the content of the table. If there is a fk error that needs to be displayed, is there a way to show this error on the page that displays the content of the table and not the page that has the delete button after the user hits the delete button?
Thanks,
Tim

First, I would not be using ParameterExists as this function
has been deprecated since CF 6 I believe and might not work in
later releases, use IsDefined("Add") instead.
Now on to your question, you cannot insert any values into
fields such as autonumber or "auto identity" fields, the database
inserts these values themselves when a new record is created.
For this purpose I would not use <cfinsert, instead use
<cfquery to insert into your database.
<cflock timeout="30" throwontimeout="yes"
name="InsertIntoConf2007Registration" type="EXCLUSIVE">
<cftransaction>
<cfquery name="Insert" datasource="DSSurvey">
INSERT INTO Conf2007Registration (Name, Email, County, Title,
Phone, Address1, Address2, PO, CityStateZip, Guests, Golfyes,
Company, Allergies, Vegie2, Social, Comments)
VALUES ('#form.Name#', '#form.Email#', '#form.County#',
'#form.Title#', '#form.Phone#', '#form.Address1#',
'#form.Address2#', '#form.PO#', '#form.CityStateZip#',
'#form.Guests#', '#form.Golfyes#', '#form.Company#',
'#form.Allergies#', '#form.Vegie2#', '#form.Social#',
'#form.Comments#')
</cfquery>
<!--- @@identity is a built-in variable that holds only
the most recent autonumber or auto identity value from a table, for
this reason we wrap the entire section in a cflock so that we do
not run into "race conditions" where 2 users could get the same
value or swap values. Once an insert starts everyone else has to
wait until the lock is finished so you guarantee that the newly
inserted autonumber is actually correct for that insert --->
<cfquery name="GetNewID" datasource="DSSurvey">
SELECT @@identity AS TheNewlyInsertedID
FROM Conf2007Registration
</cfquery>
<cfoutput>
Your registration number is #GetNewID.TheNewlyInsertedID#
</cfoutput>
</cftransaction>
</cflock>
