If you add a field that marks them as specials, then >you can create a price formula that does the discount if it sees the >'specials' flag set.Grant's excellent suggestion of adding a field named 'specials' would be useful for another feature, too.Let's say you want WebCat2 to offer 4 'special items' each day (as you mentioned above) but you don't want to repeat any of these specials ... until every one of your 2000 items has been offered as a special at least once.In this case, you can mark each of the special items by putting a T into the new 'specials' field as it is offered. Then, by adding &nespecialsdatarq=T to your search string, this will prevent previously-marked specials from being included as future specials ... until all the items in the database have been offered as specials at least once.With 4 specials per day and a total of 2000 items, it will take you 500 days to offer all your items as specials the first time ... then you can reset the value of 'specials' in all your records from T to F using [replace], and start all over for the next 500 days. Even more interesting is that you can automate the [replace] so it happens exactly when it should ...You can put the [replace] inside a [showif] context that only shows when [numfound]<4. That way, WebCat2 will reset the 'specials' value automatically ... but only after reaching the final 4 randomly-selected specials in the database.This [replace] would automatically occur at the 'proper time' no matter how many items you choose to add to of remove from your database in the meantime ... so you would never have to think about it again.In other words, it offers a completely automated solution that just keeps going and going and going ... kind of like the Energizer bunny! :)Sincerely, Ken Grome WebDNA Solutions
