Hello all, I have a little question here. I've been trying to make (self) sell ability like in TowerDeffence maps. But as results I've only got fatal errors.
(PLS no point values, I want gold to appear next to building when it's sold)
Here's some triggers of few tries of mine.
I really appreciate your help!
