title: Array conditional must be same shape as self
body: <p>I get this error when I attempt to compare to variable names such as:</p>
  
  <pre><code>compare = Search1.where(Search1UK&gt;Search1DE)
  compare
  compare.fillna(0)
  </code></pre>
  
  <p>'Search1UK' and 'Search1DE' are both variable names in which I have assigned a name to identify columns within different data frames.</p>
  
  <p>Anyone could help on this please? </p>
