Formula to Calculate Sticker Allocation per Player

[AMI B]

Hello... need some help!

I'm currently playing some online game. The game has a sticker album and each player has the option to exchange stickers with each other. Only one sticker can be sent. The sticker album contains 20 stickers numbered from 1 to 20.
So far what has been done is that the players from my exchange team would send all their data which stickers they have to send and which ones are missing to me - and I had to manually decide who sends to whom so it turns out that everyone sends a sticker and everyone gets a sticker that is missing - according to the data I got.
I want to create a formula in Excel, where I will enter the data of all the players, and then the result will be to who each player should send a sticker based on the data I entered

I would be happy for help on how to do it or what function to use
I'm pretty new to Excel...

ive added a screenshot of how i want it to look like

Welcome to the forum.

There are instructions at the top of the page explaining how to attach your sample workbook.

A good sample workbook has just 10-20 rows of representative data that has been desensitised. It also has expected results mocked up, worked examples where required, relevant cells highlighted and a few explanatory notes.

Members will tailor the solutions they offer to the version (NOT release number) of Office (Excel, NOT Windows) that you have. Please check that your forum profile is up-to-date in this respect. If you aren't sure, in Excel go to File | Account and report what it says below the MS logo at the top of that page. If your version is for Mac, please also state this. Thanks.
