An easy way to select which cart.db to use (cart0.db, cart1.db, cart2.db ... cart9.db) would be to grab the last digit of the cart value and use the db with that digit in its name, like this:[replace db=cart[getchars start=1&end=1&from=end][cart][/getchars].db& ...Of course, this assumes the visitor carries the cart value throughout his entire visit ... :)Sincerely, Ken Grome
