[support] token in code field in Display suite

Hi all, I need to change the title of a node depending on the value of the field field_project_type. I created a "PHP code" code field in display suite and added the following code: <?php if ([node:field_project_type] == 'Project') { ?> Project [node:title] <?php } else { ?> [node:title] <?php } ?> However, I get the following error: Parse error: syntax error, unexpected ':', expecting ']' in /var/www/wallfish/modules/php/php.module(80) : eval()'d code on line 1 What am I doing wrong? I can't find any correct way to get the value of that field through a token. Thanks. Bert
