Alright, so I finally got around to adding some weapons to my campaign. However, the sound effect that's supposed to play along with it doesn't work with the .tbm file I've attached below. I believe I've isolated the problem to the .tbm file, since I can force the sound to play using the play-sound-from-file SEXP. The weapon table that uses the sound works (minus the sound).
#Game Sounds Start
$Name: 192 sound.ogg, 0, 0.80, 1, 2000, 3000
$Name: 193 smallexplosion1.ogg, 0, 0.80, 1, 500, 1000
#Game Sounds End
I looked at other mods to see what they did - It looks like they just outright replace the .tbl file with their own. When I tried adding the above entry to the appropriate section in the copied sound.tbl, I ended up generating 270 errors. I feel like I'm just missing something here.

Would anybody care to help me out?
