Probably a boolean value. For instance:
If your on one team(team 1) the name should be on for your teammates, but off for the other team (team 2).
Switch sides, and now they should be on for the team 2 and off for team 1. Just search for these changing values till you get something. Every game is different, and I suk @ searching for values, so idk, but once you have the address the code for freezing it should be pretty easy.
