Let me see if I can lay out what I'm thinking, and hopefully, someone can help me figure out how to do this.

When a user goes to enter a ticket, I'd like them to have two dropdown boxes, one labeled "Impact" and the other is "Ugency". I'd then like the ticket priority to be dictated by their answers. For example, if a user chooses "work stoppage" for the urgency, and "multiple users" for the impact, the ticket automatically becomes high priority. Example two, user selects "work hindered" and "single user", the priority becomes standard. Can someone tell me if this is possible?
