well I feel stupid. Thank you though. its a lot of help

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. at cpw.mods.fml.common.LoadController.transition(LoadController.java:162) at cpw.mods.fml.common.Loader.initializeMods(Loader.java:691) at cpw.mods.fml.server.FMLServerHandler.finishServerLoading(FMLServerHandler.java:97) at cpw.mods.fml.common.FMLCommonHandler.onServerStarted(FMLCommonHandler.java:318) at net.minecraft.server.dedicated.DedicatedServer.func_71197_b(DedicatedServer.java:187) at net.minecraft.server.MinecraftServer.run(MinecraftServer.java:374) at net.minecraft.server.MinecraftServer$2.run(MinecraftServer.java:670) Caused by: java.lang.NoClassDefFoundError: net/minecraft/client/multiplayer/WorldClient at DamageIndicatorsMod.server.DIProxy.register(DIProxy.java:26) at DamageIndicatorsMod.DIMod.load(DIMod.java:97) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) at java.lang.reflect.Method.invoke(Unknown Source) at cpw.mods.fml.common.FMLModContainer.handleModStateEvent(FMLModContainer.java:513) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) at java.lang.reflect.Method.invoke(Unknown Source) at com.google.common.eventbus.EventHandler.handleEvent(EventHandler.java:74) at com.google.common.eventbus.SynchronizedEventHandler.handleEvent(SynchronizedEventHandler.java:47) at com.google.common.eventbus.EventBus.dispatch(EventBus.java:314) at com.google.common.eventbus.EventBus.dispatchQueuedEvents(EventBus.java:296) at com.google.common.eventbus.EventBus.post(EventBus.java:267) at cpw.mods.fml.common.LoadController.sendEventToModContainer(LoadController.java:208) at cpw.mods.fml.common.LoadController.propogateStateMessage(LoadController.java:187) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) at java.lang.reflect.Method.invoke(Unknown Source) at com.google.common.eventbus.EventHandler.handleEvent(EventHandler.java:74) at com.google.common.eventbus.SynchronizedEventHandler.handleEvent(SynchronizedEventHandler.java:47) at com.google.common.eventbus.EventBus.dispatch(EventBus.java:314) at com.google.common.eventbus.EventBus.dispatchQueuedEvents(EventBus.java:296) at com.google.common.eventbus.EventBus.post(EventBus.java:267) at cpw.mods.fml.common.LoadController.distributeStateMessage(LoadController.java:118) at cpw.mods.fml.common.Loader.initializeMods(Loader.java:690) ... 5 more Caused by: java.lang.ClassNotFoundException: net.minecraft.client.multiplayer.WorldClient at net.minecraft.launchwrapper.LaunchClassLoader.findClass(LaunchClassLoader.java:99) at java.lang.ClassLoader.loadClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) ... 34 more
