title: How to count the number of items and have this sustainable when I add new items?
body: <p>I am trying to create a Google Spreadsheet which is able to count the number of items, and also be sustainable when I add new items which won't affect the previous result.</p>
  
  <p>The table at the left is the data, and on the right is the result I am looking for <a href="https://i.stack.imgur.com/ucKdz.png" rel="nofollow noreferrer">Example</a>:
  <a href="https://i.stack.imgur.com/ucKdz.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/ucKdz.png" alt="Example"></a></p>
  
  <p>The two items in RED box are newly added, and the yellow cells show the results expected.</p>
  
  <p>Basically, when there is a item is bigger than ZERO, I want it to be counted. However, I don't want the previous result to change when I drag the function across.</p>
  
  <p>I tried to use the combination of =counta and vlookup, but it is not working properly.</p>
