Download the latest Motd+.zip
Extract the folder, and open it up. There should be 2 .jar files in it. MotdPlus.jar, and MotdPlusBasics.jar.
MotdPlus.jar provides the basic interface, and MotdPlusBasics provides the variables, "player", "max", and "online".
Drag both .jar files into your plugins folder, and restart the server. If you get an error on first startup, restart the server one more time and it should be fixed.
