I want player to buy kielbasa from the store for 500zl. When he does it, layer with kielbasa being visible, +1 kielbasa adds to the kielbasa global value. When player buys it again, another layer with kielbasa being visible, ect. Everything works with 500zl, but if you will buy it when you have 1000+ zl, you will instanly buy 2 kielbasas and the money system dies. What I did wrong?
