how do I make a proximity prompt work for a certain team
Can you be more specific? We don’t understand that much of a context.
You could just do:
if Player.Team == "Red Team" then
ok thanks 
btw where should the PLAYER be linked to local player?
You can just check by getting their team.
You can get the local player like this:
local Player = game:GetService("Players").LocalPlayerok thats what I had but thanks
