How do you add Lives with no codes in Game Maker 7.0 Pro?

If you want to add lives to a previous number of lives, go to the score tab and drag the "set lives" button to the table. Then type in the number of lives you want to add (ex. 5 if you wanted to add 5 lives, -2 if you wanted to lose 2) and set it to relative. This is very important because if you don't set it to relative then it will replace the last number with the new one. Unless you wanted to do that, of course.
