What's wrong with this script

[Thilock_Dominus]

Okay, I'd never been great for scripting but what am I missing in this script to get it to work? Every time I starting Dom2 up it exiting before I can get to the menu.

The script:

#modename "Miasma Marsh rider"

#Icon "Miasma Marsh Riders.tga"

#name "Marsh Rider"
#spr1 "stand.tga"
#spr2 "attack.tga"
