Silent Monsters?

[StevenC21]

Hey guys; I have an issue. My monsters and weapons that I inserted into a pk3 of my own creation are silent. I have included the file here, I would appreciate it if somebody would take a look at it and tell me what I did wrong. Thanks.

Near the bottom of this page, it says:

The #include directive cannot be used with SNDINFO, but WADs may include multiple SNDINFO lumps. In PK3 format, multiple SNDINFO lumps can be used by giving them unique extension names. For example, SNDINFO.weapons, SNDINFO.monsters, SNDINFO.ambient, et cetera.
