You can emulate it with specialized DTML methods. As an example: "url_quote": Define the DTML method: url_quote as: <dtml-var text url_quote> Ensure, there is no whitespace whatsoever before '<' or after '>'! You call this function with: url_quote(text=<your_text>)

<dtml-call "REQUEST.set('firstname', firstnam)"> <dtml-call "REQUEST.set('surname', surnam)"> Get rid of these by using the correct name in the first place!

<dtml-call "REQUEST.set('email', eadr)"> <dtml-call "REQUEST.set('email', url_quote(text=eadr))"> ...

As someone else already pointed out, you can use "_.string.replace(eadr,'@','_')" if only the '@' makes problems. But email addresses may contain other funny characters not allowed in id's. Therefore, "url_quote" is safer (but not completely safe -> '/'). Dieter
