Re: Part 2 - [showif] if variable exists

Any ideas why this would not work?I cannot see anything wrong with the code above, and no, using hideifs instead won't change anything here. If the variable does NOT exist, both sides should resolve to the same thing, [wogroup1datarq], and that means the enclosed stuff should NOT be displayed.Try removing the url context and see if that helps. I don't see why it would, but then again I generally do not wrap my tags in url contexts, I usually just do this:[showif [wogroup1datarq]![raw][wogroup1datarq][/raw]][wogroup1datarq][/showif]Just remember, Jay had a good reason for putting that url context in there. It will prevent the search from failing if your user types in a & (or some other character that needs to be url-ized) into the field this variable represents. But if your users are setting this value from a checkbox or popup menu or radio buttons, you shouldn't need the url context because you're the one responsible for creating the list of values for this variable, and you can make them all url-compatible yourself.Special Note:I've had times during development of webcat sites when my showifs and hideifs suddenly decided to behave exactly the opposite of how they should. It's some kind of webcat glitch that's basically impossible to reproduce consistently, so when I see it happen, I restart the computer, the glitch goes away, and everything seems to be fine from then on.If all else fails, try restarting ... :)Sincerely,Ken Grome808-737-6499WebDNA Solutionsmailto:ken@webdna.nethttp://www.webdna.net Associated Messages, from the most recent to the oldest:
