add text in quiz progress

sanachr

hi every one, I need to add a text in quiz progress bar that changes with evry node. I have for example if node_nid= 29 I want to display 'mini quiz', if node_nid= 30 'full quiz' ... the $variables that i have in function theme_quiz_progress has no parametre that return "node nid", how can I recuperate it to display customised text. thank you Sanachr
