I've tried hiding them with IF contexts but that seems to fail, too. >If you search a db and tell WebDNA display the value of [MyField], but no such field exists in the db, WebDNA will display [MyField] literally.If the value of [MyField] was literally [MyField] when it was written to the db, then the value of [MyField] is [MyField]. It is not an empty field.A called variable named [MyVariable] that has had no value set will display [MyVariable]. This applies to form variables as well as text and math variables. It's WebDNA's way of telling you that no such field exists, not that it has no value or is empty.When asking why something like this happens, always show us your relevant WebDNA code. HTML stuff isn't relevant WebDNA code.Glenn ------------------------------------------------------------- This message is sent to you because you are subscribed to the mailing list
