Help with login page error message please

Hi i am building my first cold fusion projec and am using bits of code from different tutorials and trying my best to understand exactly whats going on and at the same time altering each line of code to suit my project, so im learning as i build... Anyway i built a tutorial login page complete with database and datasource, tested it locally and it worked a treat. I have doctore some of it to suit my variable names and page layout and now have an error message and dont know where to start looking for the solution?
I'll start by displaying the error message i get when i click the submit button.


The Error Occurred in C:\Inetpub\wwwroot\sunshine_root\client_login.cfm: line 7

5 : SELECT clientID,clientUsername,userGroup FROM tbl_client WHERE clientID='#FORM.clientUsername#' AND clientUsername='#FORM.clientPwd#'
6 : </cfquery>
7 : <cfif MM_rsUser.RecordCount NEQ 0>
8 : <cftry>
9 : <cflock scope="Session" timeout="30" type="Exclusive">

would it be best for me to paste all the code before the head tags here or just the code for the form itself???

Is this a "Too Few Parameters" error?

Feel free to email me for help.
