Ok. I know there were no comments. I removed them to make you think (yes, that's why...).
what happens is that ColdFusion evaluates the string. Say that the string is: "Our product is #1 in 25% of the selected demographic" ..if the line were not there, after processing it would be evaluated as "Our product is #1 in #25-25#% of the selected demographic" ..which would cause a coldfusion parsing error so, what this line does is effectively escape the existing hashes, so the string becomes: "Our product is ##1 in #25-25#% of the selected demographic" ..which evaluates as "Our product is #1 in 0% of the selected demographic" which unfortunately can be true at times... ------------------------------------- SO, with comments <cfscript> ....... // escape any hashes in the existing string str_text = replace(str_text, "##", "####", "all"); // replace any percentage values with coldfusion code to // subtract 25% from existing values str_text = ReReplace(str_text, "([0-9]*)%","##\1-25##%","all"); // evaluate coldfusion code result = evaluate(DE(str_text)); </cfscript> I hope that clears things up Joel (The old-hatter cookie cleaver) -----Original Message----- From: cfaussie@googlegroups.com [mailto:[EMAIL PROTECTED] Behalf Of Matthew Sent: Thursday, 14 December 2006 1:55 PM To: cfaussie Subject: [cfaussie] Re: Regular expressions - backreference as a number Someone is a very cleaver cookie!!!
