How to remove an item from a specified inventory slot?

[dariel]

Hi all! I'm trying to make a gifting dialogue that lets you select a suitable item and give it to a lord. The item should not have any negative modifiers to be suitable. So far I've been able to filter for that using inventory slots, but when I give the item and try to empty the item's slot, I instead get an [Invalid Item] entry for that slot. How can I fix this? Thanks!

Never mind, found a solution. I just had to remove "itm_no_item" afterward. Locking.
