You may try to check the following things :
- what version of eqemu are u running, is it known to work or no with quests (check this on the forum, with the search button).
- check and recheck your syntax, start with a very basic quest, like just an say event, check if the zone crashes, add an answer to 'hail', check the quest again... once you ll be able to build a working script, the following ones will take less time (copy/paste)
- if you don't know the syntax well, try to use the questeditor (link in my sig), clickies will save you some time
- cross your fingers
