interpreted = N
texte = Well, the WebDNA parser is setup in such a way, that an exception in the equation parser will result in the ELSE clause getting executed. Not saying that this is the correct behavior though. Personally, I think it would be better to output an exception error, and stop the template processing. -----Original Message----- From: Donovan Brooke [mailto:dbrooke@euca.us] Sent: Tuesday, November 18, 2003 12:09 PM To: WebDNA Talk Subject: Re: Another IfThenElse question.. That looks like it did it Scott (though I was changing a bunch of other things at the time :-). It is working now. I do have a question though. Why does nulling out one comparison cause the else context to enact when the *second* comparison is results TRUE? I would think this would make the if statement true?
