Fewer nested contexts equals greater overall speed, right?So now all I have to use is [variableName] tags on the rest of the page, provided the page is referring to the values retrieved from a specific db record -- which is nearly always the case when using an administrative interface designed to provide access to a specific record or group of records ... :)Sincerely,Ken Grome808-737-6499WebDNA Solutionsmailto:ken@webdna.nethttp://www.webdna.net Associated Messages, from the most recent to the oldest:
