How do I make an invincible command?

How do I make a script that if I type something like "invincible/me" in the game chat, it makes me invincible.

Not going to give a full script, just the invincible part.

game.Workspace.PlayerName.Humanoid.MaxHealth = max.huge

Pretty simple. And this is not a request site..
