thanks everyone for your help

So...the tileset has NOT been set up yet?
It's a long process, but you need to do something to the priorty, x's and o's, directions, etc...here's a tutorial to help you get through it.

IF it is already set up, then you might have used a random empty square somewhere that allows your character to walk on it(left as an 'o') Then you need to only use the uppermost left blank square to 'erase' a tile you don't want to use.
