Error when loading any mod

[Lacrusis]

Hello, I am new to forge, and have done lots of research, but am still in the learning stages.  I attempted to make a forge/bukkit server, and it does run, until i put a mod into the mod folder.  This is my latest crash code:

I have no shame in saying that i have no clue how to read or research this further.  I apologize if this is a simple-minded mistake.  Thanks for any help!

Alright, simple enough.  Thank you for that.  I cant believe i didn't find that, I looked through those forums once before.  Oh well, on to the next project.  Thanks again!
