You can nest a "Repeat Selection" on a <td> tag inside of a "Repeat Region" on the <tr> tag in order to achieve Horizontal looping.
The recordset limit should be automatically updated when you add the repeated region and should stay in place when editing.
If you do want to edit it manually, don't delete it because it will be added back. Change it to 0 (zero) and then it will return all results and will keep the value when editing the recordset.
