I'm using the expression
for(var/turf/board/black/A in usr.loc)
if(A.occby=="black")
(I'm positive that occby is defined under /turf/board/black)
But it always says that A.occby is not valid.
Make sure you have occby defined.

Ooops I used ooc instead of occ
Just use a : instead of a . .

Please save us some trouble and don't. Spuzzum links to a few good explanations why in [link].

Guess you weren't that positive.
