trying to fire a remote event in a repeat loop and won’t work?

I’m trying to make it so that it always checks their score and character name to know when to fire a remote event to change their character, however this isn't working. can you see any problems?

repeat 
	wait(0.1)
	if Player.leaderstats.Mass.Value < 16 and not Player.Character == "Bacteria" then
			
		game.ReplicatedStorage.ChangeChar:FireServer(game.ReplicatedStorage.Bacteria)

		print(Player.Character)
	end
until Player.leaderstats.Mass.Value > 15

repeat
	wait(0.1)
	if Player.leaderstats.Mass.Value > 15 and Player.leaderstats.Mass.Value < 31 and not Player.Character == "Virus" then
		
		game.ReplicatedStorage.ChangeChar:FireServer(game.ReplicatedStorage.Virus)

		print(Player.Character)

	end
until Player.leaderstats.Mass.Value > 30
