Yes, there is a problem with your quests. A quest should look like this:
init_quest([some nuber],[sHORT description],[FULL description])
e.g:
init_quest(0,"Kill bandits","Erika from Fort Avernum has asked you to kill the bandits outside of town.");
After the number follows the title of the quest, and then the full description. I don't know if that has something to do with your dialog
