As Mike Tangorre mentioned, if you want to use Client variables you will need to specify where Client variables will be stored. You can either do this using the CLIENTSTORAGE attribute of the CFAPPLICATION tag, or you can specify a default storage location within the CF Administrator. However, I would generally recommend that you not use both Client and Session variables. Usually, I think you're better off just using one or the other, depending on the needs of your application. For most relatively simple applications, Session variables are your best bet. I'm oversimplifying a bit here, of course. So, what happened when you tried to use Session variables? Remember that they also need to be enabled within the CF Administrator and within your CFAPPLICATION tag using the SESSIONMANAGEMENT attribute. > Also, the most logical place for me to put an assignment for this > variable is in a CFC, but I see that Mr. Corfield does not recommend > doing this: > > "It's not that CFCs cannot access scope variables, just that they > should not in general (since it breaks encapsulation).

If you're using the Client scope, I suspect you'll get a little less value out of the idea of encapsulating access to it within a CFC, since the Client scope itself isn't stored in memory beyond a single page request, but rather is refetched for each page request from whatever storage location you specified. If you're using the Session scope, I would wholeheartedly endorse Mr. Corfield's recommendation.
