When "Item is dropped" global procedure help needed

I am making an item that when you throw it in water it changes to another item. i have a somewhat working procedure but the procedure it taking the location of the player when the player drops the item. not the location of the item itself. how do i get the procedure to take the X, Y, and Z from the item and not the player. Procedure below.
