Accidentally submitted wrong episode information.

I accidentally added the wrong cast information for a "One Life to Live" episode (January 12, 1984) and realized after I submitted that it was for the wrong date. (Contribution #200206-192332-676000). I would like to delete the incorrect cast members added and put in the ones who were in the episode. I added three other episodes which were correct, but realized this submission was not. Can this be deleted so I can re-do it correctly? Thank you in advance for helping me fix MY error.
