@ArulDevan I tried it, see screenshot. I only don’t know how to specify the Required When condition. I also tried adding refresh on change in the row/section, but didn’t work.
In the first date time, set a action to refresh section on change
In the second date time, add a when rule for required condition
Open the when rule defined as required condition for date time 2. Navigate to advanced tab. In the conditions row, you will see a small down arrow at the end. Click it and select “[property reference] has a value” condition. Select the date time 1 property in the conditions dropdown. Save the when rule.
Open the when rule defined as required condition for date time 2. Navigate to advanced tab. In the conditions row, you will see a small down arrow at the end.
See attachment in date time 2/row 2 I see this, see attachment.
