title: function which takes address() and gives value
body: <p>I want to make a cell equal to the cell above it.</p>
  
  <p>When I write</p>
  
  <pre><code>=address(row()-1;column())
  </code></pre>
  
  <p>It just writes the name of the cell above(for example for B2 it writes $B$1)</p>
  
  <p>Is there a function which inputs the address and puts the value?</p>
