I made my first brick, but it won't show up.

I made my first brick using the new tutorial in General Modification Help, and it's like a centered ramp kinda thing. Everything worked, but when I enabled my add-on, and spawned in my own server; I didn't see the brick anywhere in the brick selector.

What do I do?

In the server.cs "subcategory" is spelt "subcaregory". Simple mistake but quite a hard one to see.
