Invalid Sprite Data? Bad Sprite Names?

[Virt]

I'm making a character WAD, and when I test him out, all the sprites are invisible. Also, when I test him out, it says that the name, face, and character select screen picture have bad sprite names. Here are the names I have in for them:
BATLFACE
BATLNAME
BATLCHAR
What do I do?

Go over your WAD, look at the Wiki, and make sure you've done everything right.

May I also ask what Lump editor you are using?

I'm using SLumpEd.
