Great, I'll try that, too, Mike--thanks. I couldn't have thought of it, but of course passing parameters in the URL is the most natural thing to do... In my case there's no URL, because I load these "Web pages" locally by assigning the HTML string from the database to the revBrowser's "htmltext" property, but that can be gotten around. I'll let you know.
