title: How do I make two cells dependent on one another without circular error?
body: <p>In Excel 2013, I have cells A1, A2, and A3 along with B1, B2, and B3. Column A is a yearly calculation and Column B is a weekly calculation.</p>
  
  <p>For example, if the user updates A1 (e.g., <code>5200</code>), I want to auto-update B1 (e.g., <code>100</code>). If the user updates B1 (e.g., <code>50</code>), I want to auto-update A1 (e.g., <code>2600</code>). Likewise for A2-B2 and A3-B3.</p>
  
  <p>When I try to monitor both, it creates a circular issue and Excel crashes.</p>
