Holograms Plugin Not Functioning

I have looked into the depths of Google and Bukkit forums, but I have failed to find any understandable help. I really would like to have this plugin, but it fails to enable. I get a very long error message and need help desperately. Any help will be greatly appreciated! Thanks!

Code:

Please understand I am an amateur at coding and the likes, be gentle please. ^.^

 

not sure what the problem is but i know another plugin that does the same thing that might work for you (i use it on my server)
http://dev.bukkit.org/bukkit-plugins/holographic-displays/

 

Thanks a lot! It works ^.^

 

What plugin are you using? I would use HoloAP:

http://dev.bukkit.org/bukkit-plugins/holoapi/

It's much better then holographic displays and provides more things(Like TouchScreen Holograms that can execute commands on click)!

 

i think im going to need to change to this plugin

CraigGuzman lecraeman i just changed to holoapi

EDIT by Moderator: merged posts, please use the edit button instead of double posting.

 

Good! If you need any help let me know!

 

robrobk I am also welcome to feature requests :3

 

I would advise your plugin any day Working very well on my server!
