Update did i reverse the spell?

here is my story http://uk.answers.yahoo.com/question/index;_ylt=Ahmw0_RJhIss.ez3dqAAkzwAAAAA;_ylv=3?qid=20110628041658AAxkqDd now it is not resolved cuz im not sure wether ive reversed it or not because i put a scroll saying reverse the spell into a bag with the same type of sea rock i used to cast the spell.and after i did this i noticed the clouds were getting smaller so have i reversed my spell or is there more i have to do?
