so i have made a currency system for a game that I am making but the coins that I would collect won’t be kept if you go to a different level its just resets. anyone have a solution for this.

You can use the game instance to get data between levels. If you want to keep data between different game sessions, then you need the save game. [HTF do I? Use the GameInstance Object in Unreal Engine 4] [Save And Load Player Stats - Unreal Engine Tutorial]
