In order to do this, you will need to add a "DB Save" action to the "on submit" event to store the user's data to your database table, assuming that you have created the table using Chronoforms5 "Create table" page, then your table will have a "user_id" field which will store the logged in user's id.
Next, in order to load the record itself, you will need a "DB Read" action at the top of the "on load" event, with the "Enable Mode ID" set to "No", then use this code in the "Conditions" box:
<?php
$user = JFactory::getUser();
return array("user_id" => $user->get("id"));
?>
That should load the logged in user's info from the table, please note that this tutorial assumes that your table has only 1 record per user!
