I know it's been a few days, but for those of you following this thread....the [title_req] is coming from a form, but the problem isn't coming from when it is left blank. Everything works fine when the [title_req] is left blank. The problem is coming from when [title_req]=Anything Ending with !, because that puts two !'s in a row...and I don't think WebCatalog knows what to do with it. I've tried the following:[showif [url][title_req][/url]!][text]complete=F[/text][/showif][showif [title_req]![raw][title_req][/raw]][text]complete=F[/text][/showif][showif [url][title_req][/url]![raw][title_req][/raw]][text]complete=F[/text][/showi f]With each of the above, examples, complete=F does show, and I don't want it to. I want [title_req] to be anything but blank...not anything but blank or ending with ! Does this make sense at all?Anyway, for those of you who need to know, John Davies' solution worked excellent in this case.[showif [countchars][title_req][/countchars]=0][text]complete=F[/text][/showif]This is the only code so far that will allow [title_req] to be anything but blank.------------------------------------------------------------- This message is sent to you because you are subscribed to the mailing list
