FOB Dental Clinic Database - 2015.xlsxHello again!

Last year you really helped me out. This year I need to combine the "A" & "B" sections for each grade and so need to include a larger range of data on each sheet. I am limited to the original number of kids in the class. Now I need to double it. When I access the drop down on N3, it only includes the first half of the class. How do I expand the number of entries per class?
I also did some other changes such as sheet names and such. I will include the newest version for you.
The next dental clinic is next month and I need to get the charts updated before that time. Thank you in advance.
