Re: dumb question client variables
hi there. If I wanted to remove the value of a client variable I have set for a particular user, lets just say, emailAddress, and they check a checkbox that says, Forget my email address, would the best way to do that, be to have this code... cfset client.EmailAddress = to just zero the value out? Not entirely sure what you're trying to do, but why not use DeleteClientVariable(EmailAddress) to delete that particular client variable? This has the added benefit (albeit minimal) of one less client variable CF needs to return with every page request. Then just do an IsDefined(client.EmailAddress) to check for that particular client variable when you need to. Alternatively, you can indeed just do cfset client.EmailAddress = in your code to null out the value for that client variable, and then just do a cfif Len(client.EmailAddress) to check for a value. brain fartage on a stinkin cold rainy Wednesday Hey, it could be worse.

RE: dumb question client variables
Depends how you use it. If you want to check if available using StructKeyExists, use StructDelete(structure, key [, indicatenotexisting ]) If you want to check by Len() GT 0, then just empty out with .
