Noob here : I need help, please don't mark me as SPAM

I have been working on this for days without results.

I only want to know if someone can tell me why I get the error message : ERROR: fr245m: e:\Garmin\Test\bin\gen\006-B3077-00\source\Rez.mcgen:18,12: Undefined symbol ':FONT_SEVEN' detected.

I believe that I the symbol is correctly defined in my layout, my fnt and my xml.
