So you would need a field in your donation cdt to store the user and than search your desired donations via user. -&gt; Perhaps the totalcount is already sufficient for you as you are just looking for numbers.&nbsp;</p><div style="clear:both;"></div>https://community.appian.com/thread/85678?ContentTypeID=1Sun, 12 Sep 2021 14:39:45 GMTd3a83456-d57b-489c-a84c-4e8267bb592a:ff75c6df-c2aa-448b-8c42-872455fea8f9Stefan Helzle<p>Assuming you store each donation in database, I would just load all donations for the logged in user. Then show them in a list. Can be a grid or just some card layouts.</p> <p>Then make the &quot;donate field&quot; show only if the user is allowed to do another one.</p><div style="clear:both;"></div>
