Duplicate valiations for the repeater items(start date and end date)

[SIERRA]

Hi,

1. We have 'Seminar_Schedule' repeater field in the template (One of the Admin Control Panel Page)
2. Inside the 'Seminar_Schedule' repeater field (parent), we have 'SS_Datetime' repeater field.
3. Inside the 'SS_Datetime' repeater field (child), We have 'SS_Startdatetime' and 'SS_Enddatetime' fields.

How to do validation for 'SS_Startdatetime' and 'SS_Enddatetime' fields for below cases.

• Disallow creating duplicate items with the same date and time
• The 'SS_Startdatetime' value must not set within the range of existing items 'SS_Startdatetime' and 'SS_Enddatetime' fields.
• Similarly, The 'SS_Enddatetime' value must not fall within the range of existing items 'SS_Startdatetime' and 'SS_Enddatetime' fields.
