random team making from database of player and ratings

Hi people !

My friend and I have created a Wallyball league (volleyball played on a squash court). Every week we have more and more players and making the teams is more and more complicated and time consuming. I created this Excel file to try and generate random teams faster.

team selection.xlsx

the file consist of :

1. Jersey no. and player (A and B)
2. rating if playing (C)
3. rating (D)
4. playing on a given day 0 or 1 (E)
5. wallyball courts to generate random teams with a team rating and differential rating.

the only thing it needs is a non-repeating function (as of now, one player can be selected many times)
also, the players should not be selected if they are not playing on a given day (column E = 0)

I have to do this WITHOUT using macro (1. I'm not familiar with macros ; 2. I have a free starter version of Excel, I don't think macros are enabled)

thanks for any help !
