It is also 'false' when [aaa] does not have a pre-defined value. In fact, it is 'true' only when [aaa] has a pre-defined value that is 'blank' or 'null'.================================ Kenneth Grome, WebDNA Consultant 808-737-6499, http://webdna.net ================================------------------------------------------------------------- Brought to you by CommuniGate Pro - The Buzz Word Compliant Messaging Server.
