So I want a skript that makes a stone pickaxe named "&4TNT&cPICKAXE" mine 3x3x3 blocks. And when they person shifts and right clicks with the pickaxe it will show a gui to upgrade the pickaxe to 4x4x4. And if player has 5000 {coins} he can upgrade. If he can't the gui will close and a title will displaying saying "&4SORRY BUT YOU CANT AFFORD THAT!" I hope if shanbee can help or anyone else.
