Actually there wasn't one there. It was a "not equal" sign that got screwed up in the email. But that was one half of the problem. I wasn't aware the not equal sign isn't even a ascii character and that WebDNA uses the ! instead. Thanks. :-) I feel a bit stupid for making such a basic mistake, but perhaps I can blame it on FileMaker's programming language. Half the programming is done in the databases here and half as WebDNA in the documents, so I do mix the two languages up once in a while. ;-) > By the way, you should [url] your [field] value in both examples below > if you really want to insure that your showif's and hideif's will work > properly all the time. And that was the second half of the problem. The [field] value is actually a rather huge text block and there may well be characters in it that WebDNA would interpret as comparasion operators. Seems sanity is restored then. Again: thanks a lot! One question though: does anybody know exactly what happens when a comparasion string contains more than one chracter WebDNA interprets as an operator? Does it pick the first one as the valid comparasion operator? or the last one? or one in the middle?
