Re: Count Characters
This WebDNA talk-list message is from 2005
It keeps the original formatting.
numero = 63431
interpreted = N
texte = If your [news_body] contains comparison characters (!, =, <, >, etc) that will foul up your [hideif [news_body]=] tag - url'ing [news_body] there ([hideif [url][news_body][/url]=]) will help. Also, if your [news_body] contains HTML code, you may be truncating it in a bad place resulting in invalid HTML - use [removehtml] to strip the HTML before processing it if that's a problem.
