can't give Glass_container? Say wut?

[FlawlessHappiness]

Yea i've searched alot about this.

The way i see it

The first "" is the internal name. I need it, because the item is used in a function. = "glass_container"
The second "" is its type = What item it actually is. The item is glass_container (as in the level editor) = "glass_container"
The third "" is for the SubItemTypeName which connects to my .lang file (with the entry name: glass_container) = "glass_container"
And the fourth "" is for the item to have a picture in the inventory = "glass_container.tga"

Therefor i need all of the "". And the script is exactly like the others... with only the item name changed..
