Each X cell in the array represents an item. If you want to remove (destroy) one of the items in your inventory, Delete the cell with the item you want to destroy. In my example, each X cell contains an item name. If you want to destroy the item named "cheese" from the inventory, use the action:Delete index (Inventory.IndexOf("Cheese")) from X Axis
This finds the X index of the cell containing "Cheese", and deletes it. Here's a modification of my previous example:DemoCapx
Learning how to manipulate arrays is an extremely useful skill that is definitely worth learning.
