Forge Server Can't Run Mods Please Help!

[Lmskullfighter]

Hey, so I've been trying to add mods to my server for two weeks now and I can't seem to get around this problem. I have installed forge and the forge server, at this point the server works. As soon as I add a mod to my server I get an error and the Server can't be joined and won't run. This is the error I keep getting and I've looked everywhere but I can't find a solution. I am using 1.7.2 for Forge and for Minecraft as well as the server. The mod I'm using works on single player but I can't get into my server once it's added. The mod is the Damage Indicators Mod version 1.7.2. Any help will be helpful I am completely stumped at this point. Thank you.
