Let me make sure I understand your validation rules correctly... From what I've gathered, the string must:- Consist solely of upper and lowercase English letters from A-Z, commas, apostrophes, hyphens, and space characters.- Not contain more than one space character in a row (although multiple spaces can be separated by other characters).- Not contain more than one comma in the entire string.The following regex follows the above rules:^(?![^,]*,[^,]*,)\x20?(?:[a-zA-Z',-]+\x20?)*$Regards,--Stevehttp://badassery.blogspot.com/> Subject: Help with RegEx validation ...> From: [EMAIL PROTECTED]> To: [EMAIL PROTECTED]> Date: Wed, 11 Apr 2007 22:07:02 -0700> > So far I have this regex code> > /[^a-z\-\,\']|(\,.*\,)$/> > which should check if a string is:> contains just alpha nocase,> one or more single spaces allowed,> apostrophe and dash allowed,> just one comma allowed> > Unfortunately it doesn't work.> Any help cordially appreciated.> > contiW> -- > View this message in context: http://www.nabble.com/Help-with-RegEx-validation-...-tf3563487.html#a9953116> Sent from the Cold Fusion - RegEx mailing list archive at Nabble.com.> > >
