Not working items/blocks

[Gazghol]

I'm modding the first time with FML so i don't really know how to fix this problem.

i was trying to make some Blocks and Items, but if i try to get them ingame, it says that there is no block with this id, the items have helmet textures and no names, so i tried to fix the problem myself, but i've made it worse, it won't even show the title screen now. here is my client-log: http://gazghol.de/ForgeModLoader-client-2.log

Get the hell out of the net.minecraft.src package, and pck more unique names -.-

mhh, okay i made my own package, but it still won't work. Items aren't showing their names and their texture is a helmet, blocks aren't even existing...

sorry, as i said, i'm new to this and nobody updated the tutorials yet..

 

EDIT: Nevermind, figured it out myself, sorry for derping.
