 So, now I want to demonstrate to you the periods with fixed rows and columns. So, I am going to switch this over to a pivot table. We are going to, in our org units, we're going to just go ahead and let's just turn on all facilities. I'm going to deselect all, turn on all, then go down my levels and turn on all facilities. This is going to take a minute to load because it's a lot of data. I'm going to switch my organizational units to rows and my periods to columns. All right. And now you actually see a pivot table and you can see that I have all of the organizational units in Sierra Leone turned on, all the facilities, excuse me, and you see that I have the last 12 months. So, as I'm scrolling here, I'm losing reference to the months. As I scroll down, you see that I no longer see the months. Well, if I go now to the options menu and I go to the style tab, I have the two new options, which is fix column headers and fix row headers. If I choose fix, if I turn both of these on, you'll see that we have the pivot table and as I scroll down, look, I'm no longer losing reference to my column headers. I see that as I scroll, those come with me and I'm able to make reference to them as I move through the table.
