[Help] How to make an item(s) give the player a buff when inside a custom backpack?

[Shiverdown]

Hello everyone!

I'm pretty new to coding and having some trouble adding a perk for my modded character. She has a custom backpack that allows doll-like items to give the player a buff when they are inside the custom backpack.

I had someone help code it, but it didn't work, and I tried coding it myself, which didn't work either.

So if anyone would help me with this, it would be much appreciated.

Are doll-like items stackable? If they are not, let them listen this five events: 

"onputininventory", "ondropped", "onownerputininventory", "onownerdropped", "onremove".

Or make your backpack listen "itemget" and "itemlose".
