Working with Gui's

[fred4106]

I am attempting to follow the tutorial http://www.minecraftforge.net/wiki/Containers_and_GUIs here for tileentitys and GUI's without any luck. The two problems i have are that when i run my mod and save then reload the world, my tileentity (tinyBlock) blocks wont save. The other problem is that i cant get GUis to open. When i right click my block (tinyBlock), the java console tells me that "A mod tried to open a gui on the server without being a NetworkMod"

Thanks for the help in advance:)

 

Here is my code:

Thanks for the help.

hard to tell from your src posted but i think you forgot to register your tileEntity. Here look at my github might help you out a bit
