Zopists, I am trying to check an see if an email address has an @ sign in it as a hack way of determining validity. I checked the dtml ref guide, and found the find(S,SUB[,START]) method of the string module. I am having me luck geting it to process. I have an variable int the namespace called 'email_address' (original, huh) I then try to call a conditional like so: <!--#if "_.string.find(email_address,@)==-1"--> It's not valid! <!--#else--> It is! <!--#/if--> It can't parse the DTML because of a Python syntax error. I am probably misunderstanding the way to call the find method of the string mocule. Any ideas? Jason Spisak
