Имею файл map.h

Я этот файл включаю в DATA.H и далее реализую обьект
map my_map();

мне компилятор пишет:
error C2228: left of '.set_prop' must have class/struct/union type
c:\samples\helicopter\base.h(205) : error C2228: left of '.set_surface' must have class/struct/union type

Подскажите программеры что делать ?
