If I have to add a code in between, it messes up all of the coding and coloring on the calendar. For example, if I have the following codes: 90791, 90832, 90837. Then, I want to add 90834, but I want it numerically correct, I have to add a service at the bottom, move 90837 down and put 90834 in it's place. So, I change it to: 90791, 90832, 90834, 90837. When I do that and go to the calendar, all of the 90837s are now coded as 90834. The spots are hard coded.
