Not working on french language type

I have a bilingual drupal site setup in English and French. One of the custom made content types I have uses ANT and php to create the node title. Everything works perfectly in English, however it doesn't work at all when submitting it in French. I either get a group-0 or fr/group-0 when I should be getting groupname-groupacronym. Again this works perfect in English, the site's default language, but not at all in French.

Any and all help would be greatly appreciated.
