Multilanguage on Portfolio Detail View

Hi We extended the existing profile setup with multilanguage. So far everything works fine, only we get a issue with the portfolio detail view. Drupal says: Notice: Undefined index: de in include() (Zeile 34 von (...) profiles/drupalexp_shoot/themes/shoot/templates/node/node--dexp_portfolio.tpl.php). looking at the file we have: $language=$node->language; which seemes to hide the content in geman and french. can you help me with this issue?
Please use attached template to replace for profiles/drupalexp_shoot/themes/shoot/templates/node/node--dexp_portfolio.tpl.php. thanks!
thank you a lot!
