Need Help Deleting Item From Inventory

I’ve only ever done it maybe twice and still quite new to the engine, so I’m doing blueprint until I get the full hang of UE4 C++. I decided to follow a tutorial for an inventory system. Currently, I’m trying to craft an item using a specific item in the inventory. However, I have to find the slot index I created (slot # it is in). This is what I currently have. Please help me try to find the slot the specific item is in using the inventory array and deleting the item from the array. I really need the help
