Hello @aryanjain27 

You can create "On change client script' in the variable set, where you do the validation on values. If the validation fails please "first clear the values" and then add "error message or alerts." 

This will work because when you clear the row values the row is automatically invalid and it has nothing to add. 

Please mark my answer as helpful or accept solution if it helped in anyway. 

Regards,
