Npc dilema

hiya people
i am working on an rpg and working on npcs, now i know i could use some distance stuff and code but i would prefer hitests, i have tried to get this to work with a hittest inside a movieclip but with no luck, so could somebody change this so that the movieclip changes the box movieclip to its second frame on touch insdie a movieclip, once somebody has done that i will mention them in the credits of my game :slight_smile:
thank you :p:
