texte = >What is the syntax for using a Showif context based upon a search of>multiple fields?ShowIf is purely text-based, and has nothing inherently to do with searching. It looks at whatever text is on the left of the '=' (or other comparison, like >,<,~,^,!) and compares it to the text on the right-hand side:[ShowIf [xxx]=[yyy]] | |_____evaluate right-hand side | -- evaluate left-hand sideWhatever those [xxx] amd [yyy] WebDNA expressions become (and they can be complex lookups and such) is what gets compared. Be careful, though, because if you accidentally have '=' or '!' or whatever *inside* the text of either side, then it can confound the comparison.Grant Hulbert, V.P.
