game.Players.PlayerAdded:connect(function(player) wait(1) if player:IsInGroup(1100689)then script.Parent.Text = "Hello, Joint Recon Member!" end end) --server or local script? --and do i have anything to fix?
That would be in a Regular script placed in the Workspace. For the Text, is it in their own GUI? If not, I suggest going into their PlayerGui and changing that text so it doesn't change for anyone else. Then possibly Destroy it or clear the text.
