I am trying to add validation for my share point lists. I have List with items containing some fields [Delete Item] ,[Scored Status] and some other. I want if the item is scored than user should not be allowed to select the check box for field [Delete Item]. So I am using following formula for same but it doesn't work:
=IF([Delete Item]="Yes",
IF([Scored Status]="Scored", FALSE, TRUE),TRUE)
