So I am trying to make.....?

So this is basically the only thing I'm having trouble with, so I would REALLY appreciate if someone could clearly help.

So I am trying to make a script that allows only a certain number of players on a team

for example I only want

A max of 10 Players on the Red Team

And

A max of 10 Players on the Green Team

And if the team the person is trying to get into already has max players then the person wont be able to get into the team.

But at the same time if the game does not have a lot of players in it other member can't gang up on the other team in terms of numbers of members on that team.

So like if one team has 7 players the other team cant have 1 member, so the minimum a team can have balanced out is 2 on each team

I don't know if I explained it well, but I think I did hopefully.

I disagree about this. I mean, you can make teleporters to teleport to the team changing Spawns, and add the timer and teleport them back to team pick, Myself I had done this and succesfully made it work, it requires lots of teleporting arrangements. (Don't forget to CHANGE THE SERVER PLAYER CAPASITY It makes it lot easier.

How are you trying to change the teams? By a GUI? Touching a Brick?
