Put the following code on a test page. It works for me.

 [if cgi mv_captcha_guess]
   [tmp good][captcha check][/tmp]
   [if scratch good]
     You guessed right!
   [else]
     Sorry, try again.
   [/else]
   [/if]
   <br>
 [/if]

 [captcha length=5 function=image]

 <form action="[process href="@@MV_PAGE@@"]">
 <input type=text name=mv_captcha_guess size value="">
 <input type=submit value="Guess">
 </form>

 [error auto=1]


Of course you will need properly installed modules:
- GD (including the GD perl modules)
- Digest::MD5
- Authen::Captcha

There is no need for any Require in interchange.cfg
as the required module Authen::Captcha is loaded
in the global captcha tag.

Good luck !


Best regards,

Ton
