Error (Hit multiple times) JAva, Minecraft!

Question

Hi, at the moment I don't know if this is possible but I couldn't find any other options. I'm currently stuck with a code for a Minecraft plugin. Can anyone help me why this isn't working? Thanks in advance!

It does not take the "setTag", also I always get an error with the setTag.
Code:

@EventHandler
public void onNameTag(PlayerNameTagReceiveEvent e) {
Player named = e.getPlayer();
if (this.plugin.list.contains(named)) {
e.setTag(ChatColor.RED + named.getName()); //error1
} else if (!this.plugin.list.contains(named)) {
e.setTag(ChatColor.WHITE + named.getName()); //error2
}

Answer 1

it is
// PlayerNameTagReceiveEvent
PlayerReceiveNameTagEvent
