Excel question on modelling

[The Pook]

I am not that familiar with Excel. Fooling around with modelling. Can anyone tell me how to keep the count current. When I insert rows to add data the count at the bottom of the master template stays at 18. I have 250 rows or so. When I filter I want it to count the filtered rows without physically entering row info in each relevant counting cell. Must be some simple thing I am overlooking. See below.

Thanks
