title: Count Index based on Multiple Conditions - Excel
body: <p>I have a table with order records for each Product Type. The columns contain information like Order Number, Customer Name, Product Category, Product, and Order Receipt Date.</p>
  
  <p>My goal is to find the quantity of orders that fall into the below conditions:</p>
  
  <ol>
  <li>New Customers Ordering any Product Category for the First Time</li>
  <li>Existing Customers Ordering from any Product Category for the First Time</li>
  <li>Reorders from any Product Category</li>
  </ol>
  
  <p>What would be the best way to go about this?</p>
