You should be able to simplify this into one easy step: [text]SOLDDATE=[math date]{[date]}-14[/math][/text] The {[date]} results in a number (days since the year 0000), from which you can simply subtract 14 days. The [math date] turns that number back into a human-formatted date (using you preferences settings). - brian On Jul 26, 2004, at 2:12 PM, David Cate wrote: > Hello, > > I'm trying to only show records that exist within the past two weeks. > If an item was sold more than two weeks ago, we don't want to display > the record. > > Can someone tell me where I've gone wrong? > > 1.
