How can i make an array of tiles? i have made a struct that looks something like this:

Code:
typedef struct _TILE {
     bool blocked;
     UINT graphic;
} TILE
and i want to make an array of this, i have tried:
TILE tTiles[10][10] but this doesnt seem to work, can someone please help me?

Thanks

[EDIT]
The initial thing works, but when i try to go:

Code:
int x=1;
     tTiles[x].blocked = true;
doesnt work
