how to use UI policy for date validation and clear that multiple field for catalog form

[rahul16]

I created a UI policy where we take dates from the form.

How to write a script that

1. if the user enters past dates then clear the selected field.(if user select start_date wrong then clear that field only not the other and same for the start_end date too)
2. if the user enters the date_start and date_end if the date_end is less than date_start then clear the date_end field.

how to achieve this with one UI policy.

I created a UI policy for all date validation conditions but I can't clear the selected field if the user selects the wrong date.

This is the catalog form date 1 is date_Start and date 2 is date_end.

Create 2 UI Policies.

1st UI Policy to clear Start Date

2nd UI Policy to clear End Date
