I was just wondering if there is such a thing as an If Exists function? The reason is the solution I am working on has a date created and surname field. What I want to do is in the validation part, put in a calculation that checks to see if the surname and first name for a person has not already been entered today. I am OK if the get entered twice on two separate days, but not on the same day.
If someone can suggest the calculation I would be most grateful.
