site setup problem with member login tutorial

Hi, i have found a great looking setup for the member registration and user login which also has components to set access levels within a site.
The address is here
I am having problems with the following error.

The data source named "clientVariables" is not a valid client storage DSN.
Please define client storage dsn via the admin pages.

The Error Occurred in C:\Inetpub\wwwroot\security\Application.cfm: line 10

8 : clientstorage="clientVariables">
9 :
10 : <!--- Declare Application variables --->
11 : <cflock scope="Application" timeout="10" type="Exclusive">
12 : <cfparam name="Application.dsn" type="string" default="security">

you'll need to take a quick look at the link below to see whats going on.
The path to the remote folder is this...
C:\Inetpub\wwwroot\security
The database named 'security' is inside the 'security' folder.(along with the com folder and other files.

I have setup the datasource, also named security, as per the tutorial.

Ive only just stated learning, it looks to me that the error is saying that there is another datasource required called clientVariables which i havent set up yet, am i right?

I had this problem a while ago.

You have to set up the clientVariables under Client Variables in your administrator page. It is not a DSN.

The settings for client variables is right under the DSN link on your administrator page in MX. Don't know about earlier versions.
