Update screen in form

Former Member

I have a new form linked to a new table made by a previous partner. The forms shows when a truck is due for maintenance with a date 3 months in the future. As there can be no program-code on a form, all the code is on the table.

When a user changes a no/yes-field to Yes, the system generates a new line in the table with a new date for maintenance, but this line is not shown immediately in the form.
First when I exit the form and start the form again, the new line is shown.
How do I show the new line right away ? I cant find any 'update or refresh screen' function.

All suggestions are welcome.
