Hi all, I'm fairly new to Gamemaker and I need help with a small problem I'm having to do with some variables. I have 2 different integer variables: global.money and amount. What I am trying to do is take away the amount variable integer from the global.money integer when I click a button. What I've tried to do is, on left click: global.money -= amount; Please let me know what I am doing wrong, any help would be really appreciated. Thank you.
