#1)start clicking some of the chech boxes one by one.

#2)The check boxes generate an alert which will say a number

#3)When the number comes, go to the bottom where it says start ,and move the dot in the radio button ,how much the top said to you. Sometimes an alert will say something to you and you will have to do what it tells you to do:-) I know it's confusing but you know what to do.
