Hello, I’m trying to make a Tower Defense game and my economy system is giving me issues. Currently I have it set to provide money equal damage dealt to enemies, a display for how much money the player has and a cost for placing towers. My issue is when I go to press the button to begin placing a tower i get the error in the Title, which prevents placement. I will include the error, the line it is referencing and other parts of the code that I believe are related. What can I do to fix this? Any help would be much appreciated.
