broken command

[hmack]

Hey guys,
im trying to install a minecraft server mod, and the last step is to sun this command:

#!/bin/bash
cd "$( dirname "$0" )"
java -Xmx1024M -Xms1024M -jar minecraft_server.jar nogui

---but it keeps giving me this:

Last login: Sat Apr 21 19:47:31 on ttys000
/Users/wsb/Desktop/server/Run.command ; exit;
henrys-macbook:~ wsb$ /Users/wsb/Desktop/server/Run.command ; exit;
-bash: /Users/wsb/Desktop/server/Run.command: /bin/bash^M: bad interpreter: No such file or directory
logout

[Process completed]

im not too experienced with shell commands
can i get some help please?

enter
