Coldfusion 8 doing both CFIf and the CFElse statement - coldfusion

Question

I am making a user signup app for an ecomerce site, but I have run into a very odd problem. When I run this code:
<cfif isValid("email", form.email)>
<cfquery name="check_user" datasource="#request.dsn#">
SELECT var_username, var_password
FROM tbl_users
WHERE var_username = <cfqueryparam cfsqltype="CF_SQL_VARCHAR" value="#FORM.EMAIL#">
AND var_password = <cfqueryparam cfsqltype="CF_SQL_VARCHAR" value="#FORM.PASSWORD#">
</cfquery>
<cfif check_user.recordcount LT 1>
<cfquery datasource="#request.dsn#" name="insertuser">
INSERT INTO tbl_users (var_username, var_password)
VALUES
(<cfqueryparam cfsqltype="CF_SQL_VARCHAR" value="#FORM.EMAIL#">,
<cfqueryparam cfsqltype="CF_SQL_VARCHAR" value="#FORM.PASSWORD#">)
</cfquery>
<cflogin idletimeout="1800">
<cfloginuser
name = "#FORM.email#"
password ="#FORM.password#"
roles = "0">
</cflogin>
<cflocation addtoken="No" url="#request.secure_url#checkout.cfm">
<cfelse>
<cfset client.error_message = "Your Email Address is already registered.">
<cflocation addtoken="No" url="#request.site_url#New-Account.html">
</cfif>
<cfelse>
<cfset client.error_message = "Your Email Address is not Valid.">
<cflocation addtoken="No" url="#request.site_url#New-Account.html">
</cfif>
What this code is supposed to do, is check to see if the email is already in the database, if its not, it then adds the email/password into the database then logs them in and moves them to the secure checkout site.
What the code is actually doing, is quite different though. It is checking to see if they are in the database, and then adding them, however, after it adds them to the database it skips the login and the cflocation and goes to the cfelse, going back to the original page "New-Account" and displaying the client.error_message.
How is it possible for the code to run the cfif check_user.recordcount and then part way through it skip to the cfelse?
Things I have done to try and narrow down whats happening-
It is getting pass the check_user statement and adding a user, because I have direct access to the database and after trying to signup a user, I delete it and try again (and notice that when I try to create it, it does create it), so I know its getting past the insertuser cfquery. I have changed the cflocation to redirect to google, but it doesnt, and I also have it show on the page whether or not I am logged in, so I know that it is skipping to the cfelse before the cflogin.

Answer 1

I would suggest commenting out all of your cflocations temporarily and seeing if your behaviour is the same. It could be that your login process doesn't finish before your cflocation starts.
Or, it could be that your page submits to itself correctly the first time, and then the second time hits the else clause.
There is nothing in your code that is obviously wrong to me.
