Query problem again

Question

Will I ever get this!
I have a form template which runs fine (it registers a user
of my discussino board):
<h2>Register here to post comments to any forum on this
site </h2>
<form action="Education - Bulletin Board - Register -
code.cfm" method="post">
<p>
<strong>Username: </strong>
<input type="text" name="user" />
</p>
<p><br />
<strong>Password: </strong>
<input type="password" name="pass" />
</p>
<p><br />
<strong>Your mother's maiden name (a security
precaution if you forget your username/password and need to
retrieve them): </strong>
<input type="text" name="MaidenName" />
</p>
<p><br />
<strong>Email address (optional - in case I need to
contact you about your posts): </strong>
<input type="text" name="email" />
</p>
<p><br />
<p>
<input type="submit" value="Register!" />
<input type="button" value="Back"
onClick="self.location='index.cfm';" />
</p>
</form>
</body>
Now I want to check if the username and password have been
taken by a previous user so I use this code:
<cfif NOT structIsEmpty(form)>
<cfquery name="CheckUserName" datasource= "Education
Forum">
SELECT UserName, Count(UserName) as Duplicates
FROM ForumUsers
WHERE ForumUsers.UserName=#form.user#
GROUPBY ForumUsers.UserName
</cfquery>
<cfquery name="CheckPassword" datasource= "Education
Forum">
SELECT PassWord, Count(PassWord) as Duplicates
FROM ForumUsers
WHERE ForumUsers.Password=#form.PassWord#
GROUPBY Password
</cfquery>
I just count how many times the password has been used. If it
has been used more than once I'll later ask the new user to enter a
different password. Unfortunately, Coldfusion has a problem with
this query. Specifically, it gives me the error:
Access Driver] Syntax error (missing operator) in query
expression 'ForumUsers.UserName=jimmy GROUPBY ForumUsers.UserName'.
The Error Occurred in C:\CFusionMX\wwwroot\Education\Bulletin
Board\Education - Bulletin Board - Register - code.cfm: line 7
5 : WHERE ForumUsers.UserName=#form.user#
6 : GROUPBY ForumUsers.UserName
7 : </cfquery>
8 : <cfquery name="CheckPassword" datasource= "Education
Forum">
9 : SELECT PassWord, Count(PassWord) as Duplicates
SQL SELECT UserName, Count(UserName) as Duplicates FROM
ForumUsers WHERE ForumUsers.UserName=jimmy GROUPBY
ForumUsers.UserName
DATASOURCE Education Forum
VENDORERRORCODE -3100
SQLSTATE 42000
I've run into this before, but I don't seem to be able to
grasp the general principle involved.
I'd be very grateful if someone could explain the error in
this particular case and how I can avoid the problem in the futre.
Thanks, once again, very much in advance.

Thanks for the suggestions. I've changed the code to
incorporate the advice as far as I can. It now reads:
<cfif NOT structIsEmpty(form)>
<cfparam name = "form.user" default = 0>
<cfparam name = "form.password" default = 0>
<cfparam name = "form.Email" default = 0>
<cfparam name = "form.MaidenName" default = 0>
<cfquery name="CheckUserName" datasource= "Education
Forum">
SELECT Uname, Count(Uname) as Duplicates
FROM ForumUsers
WHERE ForumUsers.Uname='#form.user#'
GROUPBY ForumUsers.Uname
</cfquery>
<cfquery name="CheckPassword" datasource= "Education
Forum">
SELECT Pword, Count(Pword) as Duplicates
FROM ForumUsers
WHERE ForumUsers.Pword="AK"
GROUPBY Pword
</cfquery>
Unfortunately, it still fails giving me the same error:
Access Driver] Syntax error (missing operator) in query
expression 'ForumUsers.Uname='adk' GROUPBY ForumUsers.Uname'.
The Error Occurred in C:\CFusionMX\wwwroot\Education\Bulletin
Board\Education - Bulletin Board - Register - code.cfm: line 11
9 : WHERE ForumUsers.Uname='#form.user#'
10 : GROUPBY ForumUsers.Uname
11 : </cfquery>
12 : <cfquery name="CheckPassword" datasource= "Education
Forum">
13 : SELECT Pword, Count(Pword) as Duplicates
SQL SELECT Uname, Count(Uname) as Duplicates FROM ForumUsers
WHERE ForumUsers.Uname='adk' GROUPBY ForumUsers.Uname
DATASOURCE Education Forum
VENDORERRORCODE -3100
SQLSTATE 42000
I think its just a SQL error as I get the same failure
message if I replace '#form.user#' with say 'GAK'.
Any further suggestions would be greatly appreciated.
P.S. I'm still a novice, so how would I use
<cfqueryparam> tags here?
