Random means truly random, in the sense that it is possible to pick the same one several times. There are a couple of solutions:1) Make 2 databases, with some of the ads in one, and different ones in the other 2) A very tricky technique that encloses your entire page inside a random search with max=2[math]whichItem=1[/math] [search db=RandomAds.db&SEARCHCRITERIA&max=2] [founditems] [showif [math]whichItem[/math]=[index]] [adBody] [/showif] [/founditems] [math]whichItem=2[/math]... the entire contents of your HTML page here ...[founditems] [showif [math]whichItem[/math]=[index]] [adBody] [/showif] [/founditems] [/search]This guarantees uniqueness because the search finds 2 items, and then displays the 1st one at the top of the page, and the 2nd one at the bottom.Grant Hulbert, V.P.
