title: PowerApps Patch statement to clear a lookup column
body: <p>I have a canvas app that refers to two Dataverse tables: Households and People.</p>
  <p>People has a lookup column, &quot;Household&quot;.</p>
  <p>When the PeopleList gallery (gal_PeopleList) is filtered by household, an 'x' icon becomes visible in each record which I'd like to remove the person from that household (I have a confirmation routine in place to prevent accidental removals).</p>
  <p>I can't get the Patch statement to work. If it's generating an error, I'm not seeing it. But it's not clearing the &quot;Household&quot; lookup column in the &quot;People&quot; table.</p>
  <p>Here's my failing code:</p>
  <pre><code>Patch(People,
      First(Filter(People,Person=gal_PeopleList.Selected.Person)),
      {
          Household: Blank()
      }
  );
  UpdateContext({ShowPopup:false});
  </code></pre>
  <p>Searching around has shown me how I can change that &quot;Household&quot; to another record, but not how to clear it or set it to blank or null.</p>
  <p>Grateful for any help!</p>
