Formula needed for a matrix

Hi everyone, this is my first post and I hope someone can help me.

I need to automate the task of filling out a matrix which counts for each country how many calls they have been on with every other country for just 2 funding frameworks. Using filters I have manually counted for Austria the number of calls they have had with Belgium and Bulgaria to demonstrate. However, to do this manually for all 28 countries will take too long so I need a formula that will use the variables in the following columns:

Column U: “ERA-NET Cofund” & “ERA-NET Cofund (unfunded call)”
Column Z: 1 (some countries have more than one funding organisation in a call so they have been numbered 1, 2, 3 etc)
Column Y: 2 countries eg Austria & Belgium
Column M: Only count Joint Calls for both countries

I have tried using COUNTIFS but it returns 0 when there is more than 1 criteria to be counted in the same column (U and Y). The other problem I have is with column M, I only want to count the Joint Calls for both countries but I don’t know how to count duplicates only or to ignore unique.

I have attached a sample of my Masterfile to show what the data looks like.

Thanks
